It looked challenging to begin with, but it turned out to take me less than five minutes. It feels so good to put geologic understanding of the landscape to work (plus a good familiarity with Google’s satellite coverage). Here’s my answer.
yep, you got it again….that is the northeastern part of the San Rafael swell, a Laramide structure in central Utah that exposes Triassic strata in its core (if i remember) up to Cretaceous stuff on its edges. Interstate 70 goes right through it, and the San Rafael river, which you can see in that image, cuts a beautiful canyon creating a Canyonlands-like landscape.
i thought this one might take more than a day…i’ll have to step it up a notch next time
Brian Romans is a geologist and assistant professor at Virginia Tech. He uses this blog to share photos from the field and write about interesting research in Earth surface processes and sedimentary geology.
the Virginia Tech contingent is going to the Pirates-Cubs game tonight, and then we have a 4-day field trip looking at PA geology. -- 6 hours ago
great #ACE2013 this year -- my students did awesome with their posters, my talks went well (I think), and tons of great chats with others. -- 6 hours ago
