SEATTLE -- Mountain climbers and bloggers have posted videos on YouTube this week of dangerous rock and ice slides on Mount Rainier.

The blog Mount Rainier Climbing posted a warning to fellow mountaineers on Monday. They recommend climbers avoid the Nisqually Glacier all together, where the slides are occurring.

Videos posted on YouTube were taken from Camp Muir, a base camp and rest-stop for climbers headed up the mountain.

Park rangers on Mount Rainier have not closed the area or the mountain yet due to the slides.

June, July and August are usually the most popular time for climbers to attempt to summit MountRainier because of favorable weather.
