The roof of the Summit observation building on Haleakala sustained heavy damage during last week's winter storm, which produced 80 mph winds.

"We're still assessing all the damage and hoping to get all the trails open by the end of the week," said Dominic Cardea, national parks spokesman. "We had a lot of wash off on the trails and there is huge water in the stream from the runoff. We're hoping everything will be restored to normal by the end of the week."

The Summit Restrooms and Visitor Center are now open again after suffering power failure and water damage, Cardea said.

One area that still needs repairs is the summit observation building. Wind gusts of 80 mph tore the roof off the building, littering the summit with shingles. Most of the shingles have been cleaned up, Cardea said, but the roof still needs repairs.

Other damage, Cardea said, was caused by the large amounts of rain that flooded the Sliding Sands Trail and left the pathway destroyed.

"The trail damage was extensive," said Chief of Maintenance Mark Rentz. "We are concentrating every resource available, but it is a big job."

Sliding Sands remains closed due to safety concerns.

Crews were assessing the wilderness cabins for damage today. Permits are being issued into the wilderness for Holua Cabin only. Backpackers can enter the wilderness via the Supply Trail by Hosmer grove.

Hosmer Grove Campground and Nature Trail is open. Campers are advised to check in at the visitor center for weather updates. Falling branches are a hazard in high wind conditions and for this reason the campground and trail were closed last week.
