Morro Rock
(these two pictures were taken by me above the natural history museum)
this week's assignment was to see a volcanic geographic feature, and a quick google search told me Morro Rock is a volcanic plug. I didn't go up to the rock this time, but I've been there plenty of times to know that the rock looks like.it looks like it's made of granite (an igneous intrusive rock) and is a protected space for Peregrin falcons that nests in the rocks.
MorroBay.org (Morro Rock (morrobay.org)) tells me that the rock formed about 23 million years ago and has long been extinct, and is one of the "nine sisters" of volcanoes that stretch along the coast of SLO county.
because its been extinct for so long, I can't find anything about what it was like as an active volcano, but my searching did reveal that "Weird Al" Yankovich wrote a song called Take Me Down in 1978 about San Luis and SLO county, which is neat. I've been a fan of his since I was little and I had never heard of this track and its pretty neat.
