(CNN) — Rescue teams were searching Thursday for three missing hikers in a pair of adjacent national parks in California.
About 45 people were looking for the three men in and around Mount Whitney, in Sequoia and Kings Canyon national parks, the National Park Service said.
Phillip Michael Abraham, 34; Dale Clymens, 45, and Stevan James Filips, 45, set out at 4 a.m. Monday with plans to hike to Mount Whitney, the park service said.
Rough weather has hampered the search for them; snowstorms have dumped from 1 to 3 feet of snow in parts of the parks.
According to the National Park Service, Abraham was last seen wearing a gray and black jacket, khaki pants, a headlamp, glasses and a black stocking cap. He carried a black backpack.
Clymens wore green cargo pants, a black jacket with gray trim, a blue stocking cap, blue undershirt and a headlamp. He used red hiking poles and had a red backpack, the park service said.
Filips wore black pants, a black-over-blue jacket, gray scarf, black stocking cap and an olive green undershirt. He also used hiking poles.
