The site of the VRT in its historic and current use, biological and geological importance and uniqueness, and varied and remarkable lives, events and artifact associated with its ground, is a complex physical, visual, perceptual, geography that embodies the history of Ventura County.  The art plan takes the same form as the site, asserting itself most directly in a sequential series of moments and apex points, witnessed as 33 distance demarcating Midden Markers, that, in their variation and multiplicity, reflect that of the site, and its place in the successively largess spheres of the city, the state, the nation and the world. These varying shaped and colored pre-cast concrete herms with archeological oil industry artifacts gracing the tops are spaced every 1/2 mile proceeding west to the coast and every 0.5 kilometer advancing inland. They are inscribed with 33 different definitions and 33 examples of the word “mark.”
