MOUNT CHARLESTON, Nev. (AP) — A ski area near Las Vegas could get a winter sports makeover and add summer thrill rides and zip lines under a plan that federal officials have posted for public comment.

The Las Vegas Review-Journal reports the Lee Canyon plan posted Aug. 17 by the U.S. Forest Service includes $35 million in Lee Canyon upgrades.

The public has 45 days to comment.

The plan would more than double the ski area, add chairlifts, downhill runs, parking and snow-making, improve or replace buildings and upgrade the water system.

It also includes bike trails and a thrill ride called a "mountain coaster."

The Mount Charleston attraction was formerly called the Las Vegas Ski & Snowboard Resort.

It's about 50 miles northwest of the Las Vegas Strip.
