PINKHAM NOTCH, N.H. – Mount Washington has recorded its first avalanche of the season.

Snow rangers say a climber descending Yale Gully on Monday triggered a small avalanche below him.

The rangers advised that traveling through small snowfields can put hikers into or underneath unstable snow.

A general avalanche advisory for the mountain, which has the highest peak in the Northeast United States at 6,288 feet, expires at midnight Thursday.
