POINT HOPE, Alaska — This is one of the most remote towns in the United States, a small gravel spit on the northwest coast of Alaska, more than 3,700 miles from New York City. Icy seas surround it on three sides, leaving only an unpaved path to the mainland.

Getting here from Anchorage, about 700 miles away, requires two flights. Roads do not connect the two places. Basics like milk and bread are delivered by air, and gas is brought in by barge during the summer.

“I don’t know if people even know that we exist,” said Daisy Sage, the mayor.
