Album of Bald Hill Field Trip

Selected photos from a spider collecting field trip to Bald Hill, southwest of Monroe, Washington (peripheral to Lord Hill Regional Park) on 13 October 2007. At one time this must have been a great habitat, before it was over-run by invasive blackberry and the owners started quarrying away the natural balds of Bald Hill. Despite these disadvantages, prime spider season ensured a good catch of 40 species, but lacking any rarities. My camera's batteries died before I got any shots of the balds or the quarry; I'd hoped to get more shots of transcolored maples too. Photos by Rod Crawford.
