Album of Elwha Gravel Bar Field Trip

On the first official field expedition (1-2 April 2008) of the Elwha River Biological Survey, Laurel Ramseyer and I collected on a large gravel bar just outside the National Park boundary and at two other sites, besides sampling pitfall traps from previous trips. This page is dedicated to the gravel bar site, with stream cobble habitat on both banks and an island with low alder growth (the larger trees on this island in the 1994 aerial photo are gone). The large gravel bar wolf spiders we sought were immature, but aquatic insects were to be had and the moss in shady areas yielded good spiders. Weather on April 2nd was just about perfect. Photos by Laurel Ramseyer and Rod Crawford.
