People like to build in pretty places. In Billings, Montana (where I spent the first eighteen years of my life), there are plenty of big houses along the Rimrocks, a cliff that forms the northern border of much of the city.
Part of the landscaping for these expensive homes is the sandstone boulders, many of which are the size of a bus. One of the hazards, of course, is that those rocks didn’t get to their present locations gently.
From the Billings Gazette: Billings home demolished by falling rocks.
There was a man in the house when the rock hit it, but thankfully no one was hurt.
The house was on Granite Avenue, but the rock was most certainly a piece of Late Cretaceous Eagle Sandstone.
Grace and Peace, and don’t build your house too close to the cliff.
