After the unexpected dive to 300 feet in 5C water.

On 9 August 2017, Peter Norris assisted me in making the deepest underwater cave dive in Canada. The cave was a lead that had been sitting for many years with nobody checking it. That might have been due to the very small entrance restriction. After moving rocks, I was able to squeeze in to make the first exploratory dive on 5 August, and on the 9th, we returned to make the last exploration dive for the trip, and move a whole lot more rocks.
