Several
people have asked me how much damage the Florida Fire caused.
Like them, I’ve heard the figure of 23,000+ acres burned and
I’ve studied the fire maps posted on the
Florida Fire website. It all seemed scary, so I decided to
go take a Sunday hike along the length of the Santa Ritas to see
how bad “my” mountain has burned. After the hike the short
answer is: yes, there has been some devastation and no, it’s not
as bad as we thought. The long answer is found in my hike diary
for Sunday, July 24.

Madera
Canyon is still closed to all persons except for residents who
live in the canyon, so I couldn’t drive there. I’ve seen reports
that Madera Canyon was untouched by the fire. There was some
brush cleanup and tree thinning around the houses and cabins but
otherwise the canyon apparently looks the same as it did before.
Since I
couldn’t drive into Madera Canyon, I headed for a trail that
would take me into the mountains high above Madera. The trail
head for Agua Caliente Trail is about three miles south of
Elephant Head and leaves a dirt road at about 4600’ elevation.
Starting at 6:15 am, I reached Agua Caliente Saddle at
7300’after two miles of a steep trail. With the high humidity
yesterday morning, my clothes were drenched in sweat by the time
I reached the saddle about 7:30. From the saddle, which is
actually on the north face of Mt. Hopkins, I could look directly
down into Madera Canyon and look straight across the canyon at
the west slopes of the main ridge of the Santa Ritas, which we
can see from Green Valley.
There was
no fire damage where I was. The fire never got to the west side
of Madera Canyon. Looking down, I could also see that the fire
never got to the floor of Madera Canyon or within a mile of the
end of the road in Madera. Looking across to the west slope of
the Santa Ritas, I was first struck by how much green there was.
Yes, there were some blackened areas where the fire had burned
and killed all the trees. The largest black area was on the
southwest slope of Mt. Wrightson in an area south of Josephine
Saddle. The second largest area I could see from this vantage
point seemed to be a triangular shaped drainage above Bog
Springs (if my geography is right). Otherwise there were several
black areas in the forest but they all seemed to one to five
acres in size. Most of the black areas were up high near the
crest of the mountain range.
Of larger
extent were several areas that appeared brown. These were areas
where the fire came through and stayed on the ground. It did not
burn the branches or the oak leaves or the pine needles on the
trees. Nevertheless the heat from the ground fire killed the
leaves and needles making the area look brown, the color of dead
vegetation. Some of these areas will recover as some trees will
grow new leaves and needles. Undoubtedly some other trees will
die from the stress, but there is hope for much of the brown
areas.
But the
predominant color I saw from my vantage point at Agua Caliente
Saddle was green, the color of areas untouched by the fire. Of
the whole west slope of the Santa Ritas from the mouth Madera
canyon to south of Mt. Wrightson, I would estimate the black
areas at 10%, the brown areas 20-25% and probably 2/3rds of the
slope is still green. This was great news. More discouraging was
my view of Josephine Peak. All I could see was its west face and
it appeared to be toast. Here at Agua Caliente Saddle, bird life
seemed plentiful. I saw American Robin, Townsend’s Solitaire,
Spotted Towhee, Bewick’s Wren, and even a rare bird, a
Black-capped Gnatcatcher.
I then
hiked the Agua Caliente Trail three miles from Agua Caliente
Saddle to Josephine Saddle. The trail traverses the eastern
slope of Mt. Hopkins. I saw no sign of fire along the trail
until just before the first saddle between the Madera drainage
and the Josephine Canyon drainage, about a half-mile before
reaching Josephine Saddle. In this area a ground fire had come
through that did not get up into the trees so the fire damage
was limited to just a couple feet off of the ground. Here, I
smelled smoke and found a stump still smoldering and smoking. By
the end of the day I would find over two dozen smoking stumps.
From this
point on I would see evidence of ground fires most of the way to
Josephine Saddle. I was in one of the “brown” areas. As I passed
Jack Mountain, I expected to see burned trees because I had
heard on the TV that Jack Mountain was burning but I saw little
evidence of it. Later when I was higher on Mt. Wrightson, I
could look back at Jack Mountain and see some burned areas on
the south side.
At
Josephine Saddle the fire had touched the land very lightly. Not
even all the pine duff on the ground was burned. I suspect that
after a month of monsoon rains there will be no evidence of fire
at Josephine Saddle. From the saddle I headed up Baldy Trail
towards Baldy Saddle. On the first half of this trek I
alternated between areas of no fire and areas of light to
moderate fire damage which burned only ground fuel or
occasionally small trees up to four feet tall. At the halfway
point, just below Bellows Spring, the trail turned right into a
north-facing canyon. There I could look northward and see a few
1-3 acre patches of black, burned forest. Bellows Spring was
totally in the green area and from there all the way to Baldy
Saddle I spent much more time in green areas than I did in
brown.
For those
not familiar with Baldy Saddle, you can see it from Green
Valley. It’s that small downward notch in the ridge just north
(left) of Mt. Wrightson.
At Baldy
Saddle itself I stopped in an area of green. The saddle was
untouched. I could still sit on the same large log and snack on
my trail mix. The only change was now the log was orange from
the slurry drops of fire retardant. However, my island of green
at Baldy Saddle was quite small. There were black areas to the
north and south and especially to the east down the east slope
of the Santa Ritas. Obviously a hot tongue of flames had come
right up the drainage to Baldy Saddle.
I
continued up the Baldy Trail towards the summit of Mt. Wrightson
and quickly reached the small grove of Douglas Fir trees. Most
had been burned but a few survived. Immediately thereafter I
entered a black zone where everything had burned, even the
largest trees. In this area I expected to find a large 20” log
across the trail that I had to climb over every time I hiked up
to the summit but the log was gone, all burned up with not even
a pile of ash left. I noticed throughout the black zone that
logs and fallen trees were totally consumed. There were no piles
of charcoal or ash. This black zone lasted until just before I
left the area of large trees and entered the rocky area on Mt.
Wrightson, which has only small brush. Even here there was life.
A Red-breasted Nuthatch saluted my from a still-green tree and a
flock of Steller’s Jays was just as raucous as ever. Yellow-eyed
Juncos were still abundant, even in the black zone. The last
three hundred feet of elevation on Mt. Wrightson were untouched
and I reached the 9450' summit for the 90th time at 11:00 am.
I expected
to look down into Madera Canyon but my view in that direction
was totally blocked by clouds filling up the canyon at an
altitude lower than my perch on the summit. I was in bright
sunlight and could look north, south, and east, but there was
nothing to the west. To the south I had another view of
Josephine Peak. Both the north and east slopes of that peak
seemed to be at least 50% black. It appeared that the southern
edge of the Florida Fire reached just beyond Josephine Peak.
Riley Saddle was obviously burned badly.
I then
backtracked to Baldy Saddle and then headed north on the Crest
Trail. This trail follows the ridgeline of the Santa Ritas north
for several miles and hugs the mountains on the east side just
below the ridge. I quickly saw that the east slopes of the Santa
Ritas had a very different fire experience than the west slopes.
On the east side there were no brown areas. Everything was
either black or green. Where fire burned, it burned everything.
Large black streaks came up the side of the mountain, frequently
in the drainages. These streaks were much longer that they were
wide. From Baldy Saddle to the Armour Spring turnoff (about 1 ¾
miles), I generally alternated hiking through black areas
100-200 yards wide and then a strip of green again. So not
everything was destroyed but within the black zones nothing
lived. A particularly bad stretch of black was about halfway
between Baldy Saddle and Pine Saddle.
Pine
Saddle can be seen from Green Valley. It is that
triangular-shaped area of tan color on the ridge a mile or more
north of Baldy Saddle. The tan is grassland that replaced a
forest burned here in 1992. About half of the burned area of
Pine Saddle is burned again. Pine Saddle is a good example of
how slowly the pine forest regenerates on our sky islands. The
earlier fire was 40+ acres. In the thirteen years since that
fire the land has grown a lot of grass and number of bushes but
on earlier hikes I could find fewer than two dozen new pine
trees. And now most of those new ones have burned.
As I hiked
the crest trail it became obvious that again the worst fire
damage was near the crest. Areas lower than me certainly had bad
burned areas, some of them stretching a half-mile or more down
the slope, but the lower burns weren’t as wide as those near the
crest.
North of
Pine Saddle I began to encounter some areas with only ground
fires so some trees were saved here even though the low brush
was all burned. Soon I could see Florida Peak. The fire started
with a lightning strike on the east side of that mountain. Being
this close to the start of the fire, I expected everything to be
burned, but Florida Peak had less fire damage than many other
areas. The top of the peak was still green. There were a number
of black and brown patches on the lower slopes but they were all
small as if spot fires had started and then died out.
In two
different areas I saw proof that not all lightning strikes start
forest fires. One dead tree had a recent lightning strike that
charred a spiral all the way down the trunk. The scar was deep
and full of recent charcoal that would have fallen off with age.
A second tree was a live pine tree that still had some green
needles at the top. The bottom four feet of trunk still showed
the lightning strike in its bark. The rest of the tree was now
hollow and open on one side for 20’ up because the lightning
strike burned the heart out of the tree. In neither of these
lighting strikes did fire spread to any nearby tree. There is a
good chance that both of these trees (and probably others) were
hit in the lightning storm of July 7th. I’ve read that 98% of
lighting strikes on trees do not start forest fires and here
were two examples. But as we found out, it only took one tree on
fire to burn many acres.
Continuing
north on the Crest Trail, I came to the junction with the Armour
Spring trail. Here around a bend I got my first look at Florida
Canyon, a north-facing canyon that empties out near the Florida
Work Station just off Box Canyon Road. I was particularly
anxious to see Florida Canyon because in my mind it is the most
special area in the Santa Ritas. Being a north-facing canyon, it
is cooler and wetter than most canyons in the mountains. Here a
relict forest of Douglas Fir trees has survived while the rest
of Arizona dried out over the centuries. Some of the trees here
are huge. On these, two people cannot stretch their arms around
the trunk to touch each other. Many of the fir trees are fifty
feet higher or more.
My first
look at Florida Canyon, at the Armour Spring Trail junction, was
crushing. The upper end of Florida Canyon is bowl-shaped like a
cirque. The entire bowl had burst into a firestorm, which
blacken everything. This was the source of one of the biggest
plumes of smoke we saw towering above the mountains in the early
days of the fire. Nothing was left up there but charred tree
skeletons.
The trail
from this junction down to Florida Saddle does not go through
the center of Florida Canyon. It skirts the east slope.
Therefore it missed the major firestorm. Although the fire
burned many trees in this area, the larger trees will survive.
At Florida Saddle there was evidence that the Forest Service had
cut down trees trying to make a firebreak of 10’ wide but the
fire just blew through. Then just below Florida Saddle (now on
the Florida Trail) I walked through an area that only had a
ground fire and almost all the trees were safe.
Hiking
down Florida Canyon area I saw a number of stumps still
smoldering and smoking. There was also an unusual
phenomenon—lots of holes in the ground, round holes of 12”-30”
in diameter, often with tunnels, 3”-6” in diameter, radiating
out from them. Entire trees had been consumed by the fire to the
point that even the underground portion of the trees burned,
even the roots.
Below
Florida Saddle there was much evidence of ground fire but it
seemed that most of the still-standing large fir trees would
survive except in one small areas where the fire burned all the
way to their 50’ tops. An interesting sight in this mid-section
of Florida Canyon were several large 24” fir trees that had
toppled to the ground with all their branches and green needles
still intact. Here the ground fire burned the trunk in two at
ground level and the tree fell. Interesting the fire did not
climb up the tree. Obviously the fire at the base of the tree
smoldered and burned for several days before the tree collapsed.
By that time the general fire had moved elsewhere so the
branches and needles never burned when the tree hit the ground.
In the
lower half of the Douglas Fir grove few of the trees burned but
all had been stressed by the heat of ground fire beneath the
giants. Due to stress, the firs dropped many of their needles to
the point that the burned ground was totally covered with a
thick carpet of needles.
As I
continued to descend Florida Canyon and leave the evergreen
forest for the oak forest, it was obvious I was going to get
wet. While still at Pine Saddle I had seen a thunderstorm break
away from the Huachuca Mountains and head for me with thunder
booming. I kept trying to hike ahead of it but it caught me
halfway down Florida Canyon. Things suddenly got exciting. It
was wet; I was wet. Thunder was crashing and echoing from the
mountain cliffs around me. When you’re caught out in a
thunderstorm there’s nothing to do but just keep moving. There’s
no tree or rock to hide under. Anything could be a target. I
knew that it was a myth that lightning only strikes the highest
object but nonetheless I took (limited) comfort from the fact
that all the cliffs around me were much higher and closer to the
clouds than I was.
The storm
was short-lived. It only wanted to get me soaked and move on. I
was now down to the lookout point that the Green Valley Hiking
Club treks to on their lower Florida Canyon hikes. Directly
across the canyon on the main ridge of the Santa Ritas was
another bowl shaped drainage. This one too had been a fire hot
spot and totally burned.
As the
slope of Florida Canyon lessened and the canyon widened out, I
came into large areas of oak that had been destroyed. The now
much lower crest of the Santa Ritas was blackened from the
streambed to the crest for more than a half-mile and all the
area I was hiking in was black. This one black area was more
than a square mile and was the largest single area of total
black that I encountered all day. Near the mouth of the canyon
the fire went right to the fence surrounding the Florida Work
Station, just yards from some of the buildings. On the west side
the fire actually went past the station on out to the mouth of
the canyon.
Just as I
arrived at the trailhead at end of the Florida Trail, Shirley
drove up with a magical sense of timing. I had finished 15 ½
miles of hiking in 8 ½ hours and I now had a ride home.
So what
did I learn?
The fire
was much worse on the east slope than on the west.
Yes, the
Forest Service said the fire burned 23,000+ acres but that’s not
the whole story. This fire has left a mosaic of burned and
unburned areas. The Forest Service measures the perimeter of the
fire and counts all the acres inside. I have no way to
accurately measure but it seemed to me that the black, totally
burned areas of the fire was perhaps 20-25% of the acreage. The
brown areas that had only ground fires were 30-40%. This left
35-40% in the green. Again there was more green on the west side
than on the east.
The fire
did not destroy all wildlife. Birds seemed plentiful even up
along the crest. I even heard a woodpecker. I found fresh bear
tracks made after the rain on the afternoon before. There were
plenty of lizards in the green areas and there were even ants
busy in some of the black areas.
There is
already some regeneration of grasses and plants. I saw some over
2” high already. Many areas are still totally black but there is
life coming back in other areas already. Interestingly, I saw
more new growth the higher I went up the mountain.
In black,
burned areas erosion of trails and hillsides is already showing
and will be a bigger problem in the future with more rains.
Although I
hear rumors that Madera Canyon will soon open, perhaps this
week, I do not expect all the hiking trails to open quickly.
Baldy Trail between Josephine Saddle and Baldy Saddle will take
a chain saw crew at least a day to clear the downed trees. Crest
Trail will take a couple days and Florida Trail much more than
that. If I were the manager of the National Forest, I wouldn’t
let the trails open for a while because more burned trees are
going to come down in the wind storms and thunderstorms of the
monsoon. Then too, some areas of the trails are going to erode
with rains.
How does
the fire damage compare to the Mt. Lemmon fires? On the whole
I’d say the damage is much lighter than what I have seen on Mt.
Lemmon. The one exception would be areas of upper Florida Canyon
with its heavy, perhaps severe, damage.
Madera Canyon is now open to the
public except that the trailheads for Super Trail and Baldy
Trail are closed. |
