Album of North Fork Skykomish River Field Trip

Selected photos by Rod Crawford from my 22 June 2016 spider collecting trip (with Jerry and Ron Austin) to the infamous Index-Galena Road Washout on the North Fork Skykomish River, northeast of Index, Washington. I started by doing a lot of sifting, which got me a decent head start on a sample; thereafter, Jerry and I sampled mostly from vegetation, both near the washout and a mile up the adjacent Sunset Mine trail. Ultimately we managed 26-28 species, but it was made hard work by a lack of Linyphiidae in the moss and litter, and dominance of invasive Enoplognatha ovata in the foliage. That trail was certainly a beautiful walk, though!
