The upper end of the larger and much deeper (15-20 feet) hole is visible as the dark green area in the upper left center of this photo. It's not clear to me just why there's a resistant ledge out to the sheer drop off of the hole, which is quite evident in the FlashEarth view. I suspect the gap between the two prominent knobs of diorite indicates the presence of another, wider, basalt dike- that trend continues as a narrowing notch behind me and to the right. Unfortunately, the last few times I've been up here, it's either been too early in the summer, and too cold, or I've just been so tired that swimming didn't seem sensible or appealing.
