I was helping my nephew Matt move a couch last week.  And passed a Monterey style home on Indian Hill Blvd in Claremont, CA that had a mini-henge.

After delivering the couch I of course circled back to take some pictures.  The house is a classical tile roofed Monterey  with a dramatic ten foot trilithon and a very mysterious hitching stone in front.

The hitching stone in the parkway has large iron bolt and what appears to be an ancient Anasazi snail design.

The single trilithon is a beauty.

Well done.
