Not _my_ fault!
Hi Doc, As Amy suggested above, a reasonable technical name for such a landform is a "flower structure" or more colloquially a "pop up". That being said, there's no truly widely used name for strucutures such as that hill which are obviously due to vertical motion in a strike-slip regime (like the San Andreas, where the particle motions are 99.9% horizontal). This is because such structures are relatively rare compared with vertical strucutures due to dip-slip faulting (where particle motions are vertical). My wife (a Ph.D. Strucutral Geologist) and I (a Ph.D. Geophysicist) both racked our brains trying to come up with the name, but both agreed that "flower structure" was pretty close when we read Amy's post. (Geology, being rooted in Natural History, is rife with agglomerated jargon. I'm sure a linguistic grad student or three could write a thesis on the etymology of the words in current usage.) Cheers, Frank Horowitz
