Red rock

Two days ago I went on a bike ride near the C & O Canal and we walked to this old stone cutting mill. Rocks were cut at the Seneca Quarry and and down the canal, which ends in Georgetown, and used for many buildings and monuments. Seneca Red Sandstone is used for the Smithsonian Castle. Beautiful.

This is for photrablogger’s Mundane Monday #75. He has sand and this is sandstone.
