This sculpture consists of 100 stones collected from 100 sites within a 100-mile radius of San Diego State University,
for use within the 100-foot circumference of the design.
The location from which each stone was collected is identified within the monument.
With a bit of photoshop work I turned this into an Alien Gate for the Weekly Challenge
