Abstract
Photos 1 - 4 – Chris Elliott is a rock slope supervisor on a construction project east of Seattle, Washington. His job is to look after a “two man” scaling crew working on the rock bluffs some 300 feet in height along the I-90 interstate just east of the town Hyak. The Washington State Rock Engineers noticed a very large mass of unstable rock along the upper rock face and asked us to take it out. Chris is loading explosives in 1½" ” holes that are 8 to 10 feet deep by 40 feet long with 1¼” x 8” power primer on the unstable rock mass that is about 300 feet above the new road construction. I-90 runs east and west longside the new construction note the containment fence and the ship containers along the highway for protection and Lake Keechelus in the background.
