|Mt. Adams (L) and Blockhouse Butte (R)|
A fascinating locale, the most obvious features in the landscape were Mt. Adams in the distance, a partially mined cinder cone called Blockhouse Butte closer by, and a grass-covered lava field in the pasture.

Noticeably short in numbers and occurrence on this expedition were Euryopis formosa (Theridiidae). After analyzing 6 years of collection data from eastern Washington, Rod Crawford and I have dubbed E. formosa a "pine cone spider" because we've found it to be the most abundant species collected from cones (27% of specimens) as well as the most frequently occurring (49% of collection sites). Yet on the this expedition, after tapping a total of 802 ponderosa cones from 9 sampling sites and collecting a total of 333 spiders, we turned up only one E. formosa. It just goes to show how misleading it could be if we tried to draw any broad conclusions from a collection period of limited duration like this 4 day expedition.
