Geopuzzle: What’s the scale?
There have been some great geopuzzles coming out of the ever-growing geoblogosphere the last few months.
I’ve got another one.
We all have hundreds or even thousands of photographs that, to the non-geologist, look like we are showing off our favorite hammer, pencil, or unidentified hand. The first thing we learned on our first field trip was to include a scale in your photograph. Nature has that pesky tendency to create self-similarity.
So … here we go … below is a photograph with scale context cropped out. While it may not be too difficult to get a general sense of scale, I’m looking for someone who can tell me precisely how tall that vertical black line is (lower right of photo). What do you win? Nothing really … I still don’t have those Clastic Detritus t-shirts made.
