South Fork Today: the Horseshoe Fire

Last night smoke from the Horseshoe Fire made sleep difficult. When the smoke eased, I slept in––until a phone call from Helen Snyder had me out of bed and out the door in 15 minutes!

We met Jim Payne and Ron Kaczor, both public information officials assigned to the fire, at the Visitor Center in Cave Creek Canyon, and they took Helen and me into South Fork for a firsthand look at fire preparations in that much-loved canyon.

I'll summarize the situation first, then go into details of what we saw. The fire is now backing into the upper reaches of South Fork, its growth slowed by light, upslope wind. Debris fall from burning trees carries it downslope. It is burning into the region above Maple Camp and is expected to reach the canyon bottom by tonight. So far (incredibly, in the view of experts here) flames running into the canyon have only been 6 inches to 3 feet high in most places––perfect for a low-intensity burn. No one expected it to behave as sedately in South Fork as it has thus far done.

Firefighters identified two scree slopes on opposing walls of South Fork and built a fire line between them. They will try to hold the fire at that line, in the upper reaches of the canyon. During the 1994 Rattlesnake Fire, they anchored the fire lines on ridgetops, only to see line after line blown away by that inferno, in a terribly frustrating loss of effort. Helen and I talked to firefighters who had also worked the Rattlesnake, and they said that they had been "well-schooled" by that fire. One laughed and said that he had never wanted to be assigned to the Chiricahuas again because of the exceedingly rugged terrain, and he has refused other assignments here. Yet he's back now, helping in South Fork.

As we drove into the main Cave Creek Canyon, we saw where fire crews have been cutting back brush from along the road, for the most part taking small trees and shrubs. Next step is to come through with a big chipper, and to reduce all the cuttings to woodchips, which are left along the roadside.

In South Fork, nothing has been "brushed" except in the immediate area of the two cabins just above the bridge. There, trees were left standing, and the undergrowth was completely removed and raked away. Sprinkler systems have been set up around both cabins (as is being done around residences in the main canyon). Otherwise, South Fork––so far––is as it was, a rich tangle of riparian habitat where the calls of nesting trogons echo from the cliff faces.

At the trailhead was a fire-jam of firetrucks, firefighters, and safety officers. One was manipulating computer images on a laptop, atop the roof of his truck. His program was the most sophisticated use of Google Earth I've yet seen. There was the terrain around South Fork, with the current fire perimeter and all the technical information about the landscape needed for studying and implementing their strategies.

Trogons are exerting their charm over the workers here. A male repeatedly landed on one of the picnic tables, in full view of crews assembling in South Fork early this morning. Several of the firefighters trailed after us to look at a nearby trogon nest. They wanted to hear about the richness of the canyon and the factors that create its high diversity. Our community is tremendously grateful for their hard work.

Whiskered Screech-Owl

A year ago on the Atascosa Highlands Christmas Bird Count south of Tucson, Alan and I encountered a little Whiskered Screech-Owl at its day roost. The owlet perched at the entrance to its roost cavity, comfortably soaking up the sunshine on that wintry day. A brief Morse code call and its yellowish bill confirmed its identity.

Yesterday that image of the basking owl, shimmering in my awareness for the past year, finally made it to paper. Here's the beguiling little raptor, rendered in watercolor and gouache.

Whiskered Screech-Owls are common within their limited habitat in the southwestern Sky Islands. Their abundance in the Chiricahua Mountains helps to boost that area's density of nesting raptors to a dizzying level. Helen Snyder has investigated nesting raptors around Portal and the Chiricahuas for years, and found that when owls are included with the hawks, eagles and falcons, the density of nesting raptors in Cave Creek Canyon far exceeds that known for any other location in North America. The next closest is the Snake River Birds of Prey Area in southern Idaho, and it boasts less than 1/4 of the density of raptors found in Cave Creek Canyon. Helen and others are encouraging the US Forest Service to give Cave Creek Canyon a special designation that recognizes its unique importance to raptors and further protects the region from oddball threats that occasionally arise.

If you will be in southern Arizona in early January and would like to join Christmas Bird Counts for these areas, you can contact the compiler for the count that interests you. For Atascosa Highlands on Sunday January 3, email Rich Hoyer (calliope@theriver.com). For Portal on Saturday January 2, email Jackie Lewis (winjac12@vtc.net). Counts for Portal and the nearby Peloncillo Mountains are run back-to-back, and many people spend the weekend attending both counts. For the Peloncillo Mountains count on January 3, please contact Alan Craig (narca@vtc.net). Yes––the dates for Atascosa Highlands and Peloncillo Mountains do conflict!
