Thousands of people attempt to hike what’s known as the PCT every year, more than 2,600 miles through California, Oregon and Washington. And as the weather warms up, hikers hit the trail. But snow is still on the ground — and above normal for this time of year in some areas, said Emily Heller, a meteorologist at the National Weather Service in Sacramento.

“Temperatures are definitely increasing but they haven't got baking hot up high yet,” SP Parker, owner of the Bishop-based Sierra Mountain Center who has about 40 years of mountain guiding experience, said Thursday. What that means for conditions: “It's going to keep on avalanching for a little while yet,” he added.

Parker said he saw a “wet slab” avalanche — where the top surface was coming off as one cohesive layer — last week near the Sierra Crest ridgeline in Rock Creek.

“Normally we don't get those in June,” Parker said.
