A congress of salamanders

No, that blog post title is not a dig at the goons on Capitol Hill. It’s apparently the proper term for a group of salamanders. We’ve been seeing a lot of them lately ’round these parts. Take a look… Red-backed salamander: Unidentified black salamander: Red eft: Another one of the unidentified black salamanders, with little white spots all over… …and missing the distal-most portion of his tail! Lovely creatures. We …

Weekend critters from Shenandoah National Park

My penchant for macro photographer of small animals continues unabated.

And lastly, a charming little red eft, a kind …

Salamander shear

Whilst discussing how to quantify strain with my GMU structural geology students recently, I hit upon a cool analogy. In order for you to understand the analogy (assuming you’re not a structural geologist), I’ll have to review some background information first. Stick with it, and I promise you a salamander at the end. Structural geologists are interested in how rocks deform. If we have some idea of the original shape …
