Yes. That grid coordinate is on the Blue Lakes trail, which is a hiking trail. Yankee Boy Basin Road goes up to the old mine area at the beginning of that trail and ends. I have climbed Mount Sneffels several times over the years. It's a very beautiful climb if you are athletic. The road up is pretty easy. You could make it in a stock SUV when I drove it about six years ago.
