On September 14, 1901 Theodore Roosevelt was climbing Mount Marcy when he got word that President William McKinley, who had been shot two weeks before in Buffalo, but had been expected to improve, had taken a serious turn for the worse.

Roosevelt rushed down 10 miles (16 km) from his campsite at Lake Tear of the Clouds to the closest town and telephone, which was outside of Newcomb, approximately 15 miles (24 km) east of Long Lake.

From there he took a legendary midnight stagecoach ride to the closest train station 26 miles (42 km) to the south, at North Creek, where he learned that McKinley had died.
