A fire burning on the north slope of Mt. Hood has been very difficult to get to because of the steep, rugged terrain. The Dollar Lake fire has stayed relatively small at 1500 acres, as of this morning. That’s thanks to weather that’s somewhat cool, but that won’t last long. “Once you get across the Cascades, they’re not having this low marine layer, so they’re still have pretty warm temperatures.” Jerre Mills with the Fire Coordination Center says the terrain is rugged, with steep slopes and heavy smoke keeping fire crews at bay. Today nearly 300 headed up to the northeast edge of the fire to try to build a defense line to slow its’ advance. The historic “Cloud Cap Inn is the only major structure threatened at the moment. It’s being protected by space age wrapping of fire resistant material that looks a bit like aluminum foil. At latest word there is another structure that's threatened: it’s "Tilly Jane" a popular building with climbers.
