Glacier Bay National Park and Preserve Superintendent Susan Boudreau announced today that a vessel speed limit of 13 knots through the water will be implemented in the middle of Glacier Bay to protect numerous humpback whales that have been sighted in this area. During the past week at least 19 different humpback whales, including a mother/calf pair, have been observed in this area. This speed restriction will apply to all vessels from 5AM Friday May 25 until further notice.
As shown on the attached map, the designated 13-knot whale waters in the middle of Glacier Bay are as follows:
Since May 15th, Lower Glacier Bay whale waters have been in effect in the waters extending from the mouth of Glacier Bay (a line between Pt. Gustavus and Pt. Carolus) to a line drawn between the northern tip of Strawberry Island and the northern tip of Lars Island, including Bartlett Cove. This boundary is shown on NOAA nautical charts of Glacier Bay. All vessels passing through this area are restricted to a speed limit of 20 knots through the water. In addition, vessels greater than 18 feet in length passing through this area are restricted to a mid-channel course or 1 nautical mile offshore.
Boaters are reminded that vessels are prohibited from operating within ¼ nautical mile nautical mile of a humpback whale in Park waters, including those Park waters outside Glacier Bay proper. In addition, vessel operators positioned within ½ nautical mile of a humpback whale are prohibited from altering their course or speed in a manner that results in decreasing the distance between the whale and the vessel. Speed and course restrictions in whale waters are intended to reduce the disruption of feeding humpback whales and to lower the risk of whale/vessel collisions. Boaters should proceed cautiously in all areas where whales are present because whales may surface in unexpected locations, posing a hazard to both the vessel and the whale. Although humpback whales sometimes tend to be distributed along the shoreline, boaters should note that whales frequently cross mid-channel as they move between feeding sites.
Boaters are advised to verify whale waters designations prior to entering Glacier Bay by telephoning (907) 697-2627 or by contacting KWM20 Bartlett Cove on marine VHF radio.
Whale waters restrictions are authorized in Glacier Bay National Park in accordance with Title 36 of the Code of Federal Regulations, Subpart N, 13.1174.

Interglacial stumps can range from 250 to 10,000 years old. Some of these stumps are remnants of forests that predate the Little Ice Age and can help researchers understand the climate history of Glacier Bay.
