Volcano?!? Really?!!?!

While driving home from a wedding in Oklahoma last weekend,

we came across this interesting landmark:

Yes, it really is an extinct volcano.

We were sad that the road up it had closed about an hour & a half before we got there.

Isn't that cool, though?

Did any of you know New Mexico had something so interesting in it's NE corner?
