The Hubbard Glacier has been rapidly advancing this summer and is now poised to block off Russell Fjord in possibly a matter of days.

Just a few weeks back, the gap was closed to about fifty yards ... now it's about the width of a basketball court.

This last occurred in 1986 and it trapped a number of porpoises and seals and set off a rescue effort that lasted for weeks.

If this occurs, salmon returning to the stream would have no way of making it up to spawn and would have severe impacts on on the watershed.
