Temperatures and steep terrain posing challenge for crew members fighting Railroad Fire South of Yosemite

Fresno, Calif. (KFSN) -- The Wind and rising temperatures coupled with steep terrain are posing quite the challenge for crew members fighting the Railroad Fire just South of Yosemite-- 920 acres have burned with just five percent containment.

"Unfortunately, today the weather conditions continuing like yesterday-- it's hot, it's dry a little bit windy so again it's challenging for the firefighters," said Dan Tune, Sierra National Forest.

Seven structures have been lost including five homes near the Sugar Pine Railroad but 100 more are being threatened.

"We're estimating approximately 200 folks have been evacuated from this area from Fish Camp to Sugar Pine including the Tenaya Lodge Folks," said Tune.

The fire forced some local middle schoolers from Bullard Talent to reverse course.

Just hours after arriving at Calvin Crest for sixth-grade camp Tuesday--the fire sparked just a few miles away. That's when administrators at Fresno Unified decided to cut the camp short and bring the 96 students and faculty members back to Fresno.

"Better safe than sorry because heaven forbid we would be there at night and have to rush out...definitely I think a good idea to play it safe," said Katherine Pape-Perez, Bullard Talent teacher.

Back near Fish Camp helicopters helped battle the flames Wednesday-- dumping buckets on the Northeast edge of the fire lines, as they waited for large air tankers to arrive

"These helicopters are pulling water from down by sugar pine camp and there's a scattering of ponds in the forest," said Tune.
