While Rod packed up his tent, I had time to admire the play of early morning light on the dewy vegetation as well as look for signs of wildlife. Perhaps this track belonged to the mule deer whose antler I'd found the day before.

Location of Bear Mtn & Bear Ck sites |
After a morning snack of Fritos and bean dip, we headed down the southwest side of
Bear Mountain to Bear Creek. Our sampling site offered a grassy field and riparian vegetation for Rod, and small clumps of ponderosas for me.

Nexus of grassland, riparian veg &
ponderosa pines near Bear Creek |
Alas, despite slogging though wet grass and hopping rose-guarded creeks, I only found 26 cones to tap. The result was only two juvenile spiders, although one was an
Ebo sp. (Thomisidae). Only a handful of adult
Ebo have been collected from any microhabitat in Washington. As for the litter, which was bone dry despite the general dewiness of the area, I got
skunked (
see Def. 5)!

Swakane Canyon |
Onward to
Swakane Canyon, a favorite spot for butterfly and, as we would soon learn, firearms enthusiasts. And now spider collectors as well. What a gorgeous place!
Our collecting area was about 2.5 miles up the canyon from its mouth on the Columbia River. Here the flat, grass-covered canyon bottom gave way to a pocket of wetlands. To my delight, ponderosa pine groves were growing on both the canyon bottom and the canyon's south-facing slope, with a few lone trees at the foot of the north-facing slope. Lots of possibilities!

The unwelcoming committee |
With a rattlesnake warning me away from the trees I'd spotted at the base of the canyon's north-facing slope, I turned my attention to three sites on the opposite side of the canyon and sampled 50 cones and a bag of litter from each.

The best and only needle litter I found |
Well, scratch that. My
plan had been to sample litter at each site. But only one site had any litter to speak of, and even so it was thin enough to read the
New York Times through. Rod speculates that the
wildfire that swept through the lower canyon in 2010 may have burned the litter. Perhaps, but that can't be the entire story since there were fire scars on the trees under which I collected my litter sample. It's a puzzler.

Callobius sp. as found in fallen cone |
In any case, these cones had spiders! From 150 cones total I collected 8 species and 67 individuals including 34 juvenile
Steatoda sp. (Theridiidae), three
Euryopis formosa and a female of the infrequently found crab spider
Xysticus gulosus (Thomisidae). Even that threadbare needle litter produced two juvenile spiders.

Swakane Canyon was my favorite place to practice target shooting. But now as I started living in Massachusetts, I have joined MA Firearms School to improve my firearms skills further.
