At the time of our last visit (1997) we were able to walk right up onto the glacier from the toe, although a sign warned of crevasse dangers. Specially equipped “snocoaches” take visitors for a drive upon the thicker section of ice higher up. The snocoaches still run and there you can get out and walk around, but down by the toe things have changed dramatically. Numerous signs warn of a large lake and several rivers that have formed below the glacier, creating more treacherous conditions there. The trail is roped off and although it is not officially closed (which would mean crossing the barrier warranted a stiff fine), you would have to ford a wide rushing creek that now flows down the side and all the way around the toe of the glacier. We also noticed that it looks to have retreated roughly a quarter of a mile since 1997. I am basing that guess upon the placement of signs and comparison of our photos from last time.
