Album of Perrinville Creek Field Trip

Selected photos from a spider collecting field trip to Perrinville Creek in Southwest County Park, Snohomish County, Washington, on 17 December 2006. Not too successful a trip (spiders probably too cold and wet to move), but almost the only nice day this month, so how could I resist going collecting? Photos by Rod Crawford.
