You can see close-up photos on the Tucson Murals Project blog in today's post Beautiful tile work at Santa Cruz River Park.
Hours: Basically, daytime hours. (Not well-lit at night… closed late nights… and maybe not too safe at night, either.)
At the northeast corner of Reid Park, and the west edge of Randolph Park — is this memorial to railroad man Epes Randolph. A big man in Tucson history, he lived from August 16, 1856 to August 22, 1921.
American-born sculptor Nicholas Lowell Burke, who was born in 1957, is listed as artist (on a plaque there). The project was funded by the City of Tucson; it's dated 2006.
Location: Northwest corner of Camino Campestre & Randolph Way.
Hours: Open 24 hours, though it's not well-lit at night.
