Graffiti & Guano

Although the cave is a quarry, and as such, doesn’t provide the ecosystem for endangered species that a natural cave would, we acquired a number of remnants from various former occupants.  Swallows used to nest in some of the blast holes and crevices each spring, the walls had a good deal of moss, and some of the two-legged visitors had left their mark in the form of graffiti.

In order to bring back the natural luster of the rock walls, we washed them down with a 4,000 psi pressure washer.  We knew we’d only be able to do this once, before construction began.  Afterwards, we wouldn’t be in a position to saturate the place with water. 

In order to reach inside the crevices near the top, we used a scissor lift and an extension wand.  Some of the blast holes went far deeper than we expected, and at full-height, the pressure of the water made the lift sway.  Doug Helmsing and Wayne Robinson worked with us, and they both have nerves of steel! 

When spraying some of the holes and crevices, we washed out years of birds’ nests, moss, mold, guano, and other debris.  Sometimes it looked like the walls were bleeding, and sometimes like they were oozing crude oil.  In the end, the natural colors and nuances of the rock surfaced, as beautiful as we expected.
