California ? Visitors trying to photograph Yosemite National Park’s famed peaks on Tuesday instead took shots of flying ash blowing in from an out-of-control wildfire burning just 12 miles outside the park.

The fire – which has destroyed 25 homes and is only 15 percent contained – has shrouded one of California’s most popular destinations in smoke at the height of Yosemite’s busiest season.

Authorities said Tuesday the blaze had charred more than 46 square miles of steep, rugged terrain since a target shooter sparked the wildfire Friday. It has also forced the evacuation of 350 homes in the towns of Midpines and Coulterville.

At summer’s peak, as many as 4,000 visitors a day stream into the park, and rangers expect the fire will keep very few people away.

Officials with DNC Parks and Resorts at Yosemite, which manages restaurants and lodging in the park, said only about 2 percent of all overnight guests have asked for refunds since Saturday, when fire destroyed the transmission line that fed power to Yosemite.
