Fog, dog, and the imaginary ice sheet

Mt Cube is one of my favorite Upper Valley hikes, it’s short, bald top, fun, and rewarding!  But most of all, it has striations, and I’m talking LOADS of striations.  We typically hike along the Appalachian Trail, but this time we tried the Rivendell Trail, a western approach, and it was awesome!  Lots of switchbacks and about half-way up, there is a small view and my friend said, “Wow!  Look at that!” (talking about the lovely view).  I was staring at the rocks, in particular the scratches on the rocks left by the Laurentide Ice Sheet 14,000 years ago, and as she said, “Wow!” I noticed a rock just covered in striations.  Clara, my furry scale, jumped up on the rock and posed.  She also started slipping down the rock, glaciers are really good at smoothing surfaces!

On this particular day, fog clung to the Upper Valley and made a flat, white surface and only the tall peaks rose above it.  This fog resembles how the ice sheet in this area might have looked.  The ice was much thicker (covered these mountains) during the Last Glacial Maximum, but as the ice age ended, the ice sheet melted, thinned, and retreated northward.  These mountain peaks would have looked like islands poking out of the ice sheet (nunataks), pretty awesome!
