As I was writing about the columnar jointing at Devils Postpile National Monument, it occurred to me that I had seen a number of geoblogosphere posts that involved the phenomenon in the last couple of days. Do posts by five bloggers make it columnar jointing week?
The youngest geoblogger, Sam at Geology Blues, has a note on Devils Tower.
Looking for Detachment's Silver Fox posted some beautiful pictures of Deep Creek Falls in Oregon, which thunder over some basalt columns. Then there were her pictures of jointing in basalt in the same general region, a Friday Mystery Photo.
Last Thursday it was Philip at Geology Blues with a picture of columnar joints in basalts on his commute in Oregon.
Though columnar joints aren't specifically mentioned, Glacial Till has pictures of the Columbia River Gorge and some of the basalt columns appear in the cliffs. Till writes of a new appreciation of the geology there.
