This image is from the west cliff of the 'cleft' exposure on the south side of Hole in the Ground, looking to the east side. I think it looks like a gorilla. An interesting question here...are two Bogus Lavas Present? Or are there a series of Greeley advances? There are three palagonite zones present, but the lava cap on the lowest has an erosional cleft that appears to be filled with gravel. There are no palagonites on the west cliff, so it may indicate a relatively long-lived emplacement history of Greeley lavas. Any thoughts?
