Effects of Altitude
Altitude sickness may develop in otherwise healthy and fit people who are exposed to rapid increases in altitude. It can develop at altitudes as low as 8,000 feet (Yosemite Valley's elevation is 4,000 feet). The risk of occurrence increases with age and with diseases of the heart and lungs.
The symptoms include headache, nausea, insomnia, irritability, shortness of breath, general malaise and fatigue. The best way to avoid it is to slowly acclimatize yourself to higher elevations, over the span of two to three days by gradually gaining elevation until you reach 10,000 feet (Tioga Pass). Avoid alcohol, sugar and high-fat meals.
Should altitude sickness develop, descend to a lower elevation. The Yosemite Medical Clinic in Yosemite Valley is experienced in diagnosing and treating this sickness.

Jenna Otter Returns to Scene of Grizzly Bear Attack

Reporting from Glacier National Park -- No one knew what to expect on the trail to Grinnell Glacier one late summer morning, but a second bull moose less than an hour out was hardly a good sign. During September and October -- mating season -- it's always best to give the spindly-legged animals plenty of room.

Expected Rule Change Would Benefit Bicycling in National Parks
November 21, 2008 - 9:07am
An upcoming National Park Service (NPS) rule change could greatly benefit mountain bicycling by improving the administrative process for opening trails to bicycles. IMBA has been asking the agency to revise its policies since 1992, because the current "special regulations" process is needlessly cumbersome and treats bicycles like motorized vehicles.
