ANCHORAGE - The 2010 climbing season on North America's highest mountain is peaking with hundreds of mountaineers hoping to reach the top of Mount McKinley in Alaska.
The National Park Service said 1,211 climbers are registered to make the 20,320-foot climb this spring and summer. That number is roughly comparable to last year when 1,161 climbers registered to scale McKinley.
On Wednesday, 448 climbers were on the mountain - most of them using the West Buttress route to the top. So far this season, 172 climbers have reached the top, making a success rate of 55 percent, slightly higher than the long-term average.
