Hiking Tips
Hiking a Steep Grade: In the Grand Canyon where you can gain 1,000' in 1 1/2 mi. they recommend allowing twice as much time to go uphill as down. Experienced hikers can usually do it in 1.2-1.5 times.

Bear Safety
General rules:

• Keep your camp clean
• Don't put food or clothes that have food smell in your tent
• Hang food from a tree or put in bear-proof containers.
• Make your presense know with noise so bears know you're comming
• Don't run or yell. Stand your ground; most charges are a bluff.
• If attacked - play dead with a grizzly - fight back with a black bear
