It was interesting to note yesterday that the small hillock on the 1550' contour to the East of 'Isle of Man' was just exposed in the middle of the lake, in contrast to my previous visit.
So, tracking the 1550' contour on shore, Colin's Concrete Construction appears to be at the most northeasterly part of the mine site.
Both the metalled road (N-S) and the gravel track (E-W) were still partially submerged at their SW ends, where they intersect is where all the goodies are. Looking at the contours I reckon another 5ft drop in water level would reveal answers.
Also interesting to note that the lake bottom is entirely above 1525' OD, so we're only talking about 25' of water depth remaining.
gives me a good excuse to fire up the bike, anyway :thumbup:
