Abell saw the forecast called for 2 to 3 feet of snow in the mountains.
She came across a trip report for Lake Valhalla, north of Stevens Pass,
on the Washington Trails Association website.
On the forum, Abell and others tried to triangulate where Groene would be,

"If she didn't get started until Wednesday," Abell wrote on Monday morning,
"she might have only got as far as Mica Lake on Saturday, when the storm hit,
one of the more inhospitable places on the PCT to be during a blizzard."
Abell once camped at Mica Lake in a snowstorm. She'd hunkered down for three days.
