The two weren't equipped to stay overnight. However, they said they were cold but OK when they used the cellphone to check in again Monday morning before its battery died.
Rescuers spotted the pair Monday at about the 7,000-foot level below McClure Rock on the lower Paradise glacier. They were about a half-mile from the two — close enough to wave — but were forced back by nightfall and dangerous conditions.

"This is what happens on Mount Rainier," Snook said. "This is why people use Mount Rainier to train for Mount Everest."
In January, four people disappeared in snowstorms on the mountain, which draws between 1.5 million and 2 million visitors each year. The bodies of three of them were found over the summer after snow melted.
