Hot Running, Cold Running

Even with a wind shell and multiple layers the gusts of wind were sharp-edged and penetrating. The weather was spectacular, but it was very windy and very cold.

My run on the PCT had started at Islip Saddle in the San Gabriel Mountains. At 8:00 am the temperature at 6593′ had been about 35 degrees. The north wind funneling through the saddle had roared through the pines, buffeting their stout limbs and telling me to put on every scrap of warm clothing I had in my pack.

The broad canyon of the South Fork seemed to act as a wind tunnel — drawing the wind from the high desert into and over the crest. Even with a gloved hand it took only a couple of minutes before my camera became too cold to hold.

I was on my way to Mt. Baden-Powell and nearly up to Mt. Hawkins. With every stride up the mountain the temperature had dropped. Father Frost had frozen the landscape and me along with it.

Had it really been just a week ago when I had broiled in 90+ degree temps on the south-facing sections of trail on the Leona Divide 50M course?

Running to Shangri-La

Well, maybe not Shangri-La, but a Lost World kind of morning on the Calabasas Peak fire road segment of the Secret Trail.

Calabasas Peak fire road traverses the rock formations on the left, descending to Stunt Road. At Stunt the route continues up the Stunt High Trail to the Backbone Trail. Here you can do an optional out and back to Saddle Peak, shrouded in clouds in this photo, or turn west on the Backbone Trail and continue mostly downhill to Piuma Road near Malibu Canyon Road. Malibu Canyon is in the distance on the right in the photo.

The panorama is from a run earlier this month. Here’s a larger version.

The Rattlesnakes Are Blooming

Although we are still experiencing a record-breaking drought, this rain season did provide a little short term relief to plants and wildlife. Compared to last year rainfall is up 27% at Los Angeles, 39% at Santa Barbara, 57% at LAX and 63% at Camarillo/Oxnard according to NWS data.

The increase in rainy season precipitation dramatically increased plant growth, the abundance of wildflowers, and temporarily increased the availability of key resources to wildlife.

Another thing it seems to have increased is the number of rattlesnakes. Over the past two years I have seen maybe two rattlesnakes total on my runs in the Santa Monica Mountains, San Gabriel Mountains, and in the Big Bear area and on San Gorgonio Mountain. In the Ahmanson Ranch – Cheeseboro area I’ve seen none.

With the increase in rainfall this season that has changed. The title photo was taken on the Leona Divide 50/50 course March 28. That day I encountered two rattlesnakes and talked to a runner that had seen three on the course the previous weekend. From March 26 to April 2 I encountered rattlesnakes on three out of four runs. Two of those were at Ahmanson and it seemed everyone I talked to on the trail was seeing rattlesnakes.

There has also been an increase in the number of encounters with non-venomous snakes as well. I’ve seen a number of gopher snakes and a California striped racer. Friends have mentioned seeing a ring-necked snake and California kingsnake.

Since the weather has cooled I haven’t encountered any rattlesnakes, but have seen their tracks. When I run, especially on single-track trails, my snake radar is on and I’m definitely on the lookout for the hard-to-see beasts.

Photography on the Run Migrated from DasBlog to WordPress

DasBlogWordPressArray

Photography on the Run published its first image, Oat Mountain Snow, more than nine years ago. Following nearly a thousand posts and the publication of thousands of images, I have migrated the content from the DasBlog blog engine to WordPress. Some work remains to be done, but the blog is fully functional and all of the content is present and accounted for.

Most DasBlog-style links to the blog’s content should continue to work. Old permalinks and date and category views have been mapped to their WordPress equivalents.

If It Looks Like a Hummingbird and Flies Like a Hummingbird…

hummingbird moth feeding on spreading larkspur

I was on the way back from Mugu Peak and about four hours into my run. I’d stopped at an exposure of Miocene age shale along the Upper Sycamore Trail. The gray-brown rubble is home to an intensely blue-purple wildflower called spreading larkspur (Delphinium patens ssp. hepaticoideum).

I’d just snapped a series of bracketed exposures of one patch of the flowers when suddenly there was the bumblebee-on-steroids buzzing of a hummingbird in front of me.

At least I thought it was a hummingbird. It sounded like a hummingbird and was about the right size. Its blurred wings were shaped like a hummingbird’s. It flew with the precision of a hummingbird, darting from flower to flower, deftly feeding on each blossom’s nectar using its oddly shaped beak.

But it wasn’t a hummingbird — it was a hummingbird moth — a white-lined sphinx (Hyles lineata). I’d read about hummingbird moths, but to have one suddenly appear and start feeding on a larkspur plant I happened to be photographing was extraordinary.

Apparently the problem of feeding on the high-energy nectar in certain types of flowers is sufficiently definitive as to have produced a very similar evolutionary solution in wildly different organisms.

The sphinx moth is described as flying like a hummingbird, but which lineage produced this elegant solution first? It may have been the moth! A trace fossil of a sphinx moth found in Early Eocene Asencio Formation of Uruguay appears to predate the earliest known Oligocene fossils of hummingbird-like birds! In any case it appears that both hovering moths and birds co-evolved with the flowering plants on which they feed and pollinate.
