Box Mountain is located in Connecticut. It is 1093.1 meters long with an average gradient of 8.1% and a maximum gradient of 14.4%. Find similar hills.

I lived less than a mile from this his for 1.5 years and never knew it was there. Of course, I also wasn't doing much riding at that point. I discovered it, like so many others, by browsing google maps in terrain mode. The gradient is quite erratic with some spikes that are higher than anything listed on the gradient map.
