The dogs and I found this hillside structure on one of our excursions on the ice of East Medical Lake in mid February 2009. Could not tell what the structure had been used for. I would say it was last used about 1920 or so. Perhaps some sort of pumping facility. Or, maybe it was a place to keep things cool in the summer and warm in the winter. A "root cellar." Seems I read there once was a residence in the
vicinity long
ago.
Whatever it was, the dogs and I were pleased to find it.
We went back onto the ice once we had finished our explorations.
