Unknown monolith

[+Grasshoppers&Ant 1]

Anyone recognize this rock? We found this in old family photos. Probably in US or Canada.

Note the person standing at the base.

I'm curious if there's an EarthCache there now.

Thanks!

It makes me think of the so-called "Policeman's Helmet" in the Drakensberg, South Africa. If it is that rock formation indeed, I can find an earth cache in the area but not specifically about this formation.

Looks like a volcanic plug. Anything like that around?
