Online registration is now available for mountaineers attempting climbs of Mount McKinley or Mount Foraker in Alaska's Denali National park.

Park officials say the system is a quick, safe way for climbers to register with park officials. Visit www.nps.gov/dena and click on "Mountaineering Information," then on "Registration Information."

All climbers attempting McKinley or Foraker are required to pre-register with park at least 60 days in advance of the climb. As of mid-April, more than 730 mountaineers had registered to climb McKinley this year. Ten climbers have registered for Mount Foraker.
