HWY 288 Hammer Sighting

I spotted this hammer on the way to work. The hammer is lying on the inside shoulder of 288 just south of the Wheeler Avenue overpass.

The hammer appears to be covered in cement. The hammer was all grey, indicating it was used in rockwork or to build and disassemble cement frames. Not a very valuable tool and defintely not worth stopping for since I have a dozen hammers at home.
