Maritime Global Net tells us:

Cruise West’s Spirit of Glacier Bay is reported to have run aground in Glacier Bay. The US Coastguard is attending the incident. There are no injuries and hull integrity has not been breached, although a boom has been deployed as a precaution. The reason for the grounding is still unknown. Passengers are being transferred to the departure port of Juneau, and the vessel is expected to re-float at high tide.
