The law signed by President Obama relaxes the National Forest Ski Area Permit Act which only allowed nordic and alpine skiing.
Now, ski resorts on U.S. Forest Service land will be able to offer non-skiing activities all year long. One of those resorts is Kirkwood in the Eldorado National Forest.
"We're excited about it. We have a lot of plans to expand our operation for summer."
Kirkwood's Michael Dalzell says the resort wants to expand a downhill mountain bike park and hold summer concerts.
But not all recreation activities will be permitted. John Heil is with the U.S. Forest Service:
"Tennis courts, water slides, water parks and swimming pools, golf courses and amusement parks. Those particular activities are not going to be permitted due to the destructive nature to the natural environment."
But things like zip lines and Frisbee golf courses will be allowed.
Nationwide, the new law is expected to create and sustain up to 600 jobs.
