First Trip to the Henkel

December 4, 2006: Scootered the main line, breathing stage bottle (FO2 32%) to Stage Bottle Rock (1800'), dropped bottle there, and switched to back gas (FO2 32%), continuing to the beginning of the Henkel Restriction at 3100 feet. Dropped scooter there, and swam through the restriction, and turned the dive. Conditions were pristine, with a high flow through the restriction. This was my first time there, and it was spectacular: rocky and low.

Gas used to Stage Bottle Rock: 46 cubic feet. Gas used from Stage Bottle Rock to the Henkel: 57 cubic feet. Total gas on ingress: 103 cubic feet. Deco obligation at warning sign: 19 minutes, reduced to 9 minutes at 10 feet on pure O2. Total time: 72 minutes. Max depth: 110'. Average depth: 72 feet. Guide: Rich Courtney.

A great day -- thanks, Rich!
