The above link is from the public broadcasting station. Some of the Seattle stations have taken shots from a helicopter that were broadcast on our local stations. The other night when I came home I saw significant light being projected on the ridge. I don't know if that was for monitoring or if they were placing the containers.
Mostly for Bruce:
This is the east side of the anticline just north of Parker. The west ridge is Ahtanum Ridge and the east ridge is Rattlesnake Ridge. I asked Nick during the field trip about Ancient Rivers Changing Course, if there was a geologic reason why the different names on either side of the Yakima River. He said no, it is one anticline with the antecedent Yakima flowing through.
During the summer the sagebrush & grass on this ridge burned. It makes the crack stand out more starkly than it would otherwise. While I'm about 3 miles from the place and in no danger, I can see it from the house.
