Hypothermia
Long periods of rainy, overcast, and cool weather are normal in Southeast Alaska. Summer daytime temperatures are usually 45-65 F, but nights stay cool to near freezing. To protect against hypothermia, a hat, gloves or mittens, and rain gear are essential. Sturdy, waterproof footgear is desirable. For more in-depth information about hypothermia see http://www.princeton.edu/~oa/safety/hypocold.shtml

Paralytic Shellfish Poisoning (PSP)
Eating mussels and clams in Glacier Bay is not recommended as the neurotoxin that causes paralytic shellfish poisoning has been found in high concentrations in the area. This is a naturally occurring toxin that affects humans as well as other animals, and can lead to sudden death.

Bears 
Glacier Bay is home to both black and brown/grizzly bears. They are wild animals and should always be considered potentially dangerous. When hiking, lessen your chances of an encounter by watching for bears and bear sign, making noise, traveling in groups, and avoiding travel at night. Food, garbage, and scented items must be stored properly. Avoid taking odorous foods. Bear-resistant food containers are required in the non-forested areas of Glacier Bay and are available for loan at the Visitor Information Station. Photograph bears with a telephoto lens; close approach is dangerous. Read about traveling in bear country for more details. More...

Giardia
Even though the water looks clear, it may contain organisms that cause a debilitating intestinal disorder. Water should be vigorously boiled for at least one minute, filtered, or chemically treated. Because of the high rate of sediment in the water in glacial landscapes, you may need to allow extra time for the "glacial flour" to settle out.

Moose Alert

Moose can be extremely dangerous

The newly arrived moose occur widely throughout thickets, meadows and open forests. The moose population has grown significantly in recent years. If you encounter a moose, use caution:

• Increase the distance between you and the moose.
• Get behind a tree.
• Change your route.

To avoid close encounters, make noise while you hike.

Baneberry, a Poisonous Plant

Baneberry , Acraea rubra, a member of the buttercup family, is aptly named. "Bane" is derived from an Anglo-Saxon word meaning "murderous." All parts of the plant are toxic. Ingesting one berry can cause numbness in the mouth and tongue. The poison in three berries is enough to kill a child. Six berries will effectively shut down the respiratory system in adults. The best rule to follow if you are sampling wild plants: If you aren't sure what it is, don't eat it.
