Crowley Lake columns
Could the column formation be caused by electrical phenomenon of a lesser intensity than a mass lightning strike? Lightning itself doesn't form straight parallel shafts.
Is there a plasma experiment that gave a similar result?
I think it is especially interesting that the columns go all the way through to the top, and beyond in some places. This can be seen in some photos, like the one in the link below.

An article about analysis of the columns mentions them containing quartz and (volcanic) glass shards., which may be a hint about past electrical activity.
