A rock and a hard place
In N-Photo issue 72, page 74, I see you have a photo of Kilt Rock sent in by Andy Dines as part of his portfolio. I’m used to seeing extra info on insects, birds and plants, but hardly ever information on the kinds of rocks in pictures. The top rock in the Kilt Rock photo looks like it may have the columnar jointing that lava or shallow intrusion may form upon rapid cooling. The bottom light-coloured layered rocks look a lot more like sedimentary rocks, such as limestone or sandstone. Does anyone have any comment on this or are all the photographers at N-Photo non-geologists? Thanks for any information! Bob Cullers, via email
Great question, Bob! Rock nuts we are not. Are there any geologists in the audience?
