Outside the mountain town of Ouray, the Gold Mountain fire increased by several thousand acres since Monday, though the fire official tasked with keeping the public informed sounded cautiously optimistic in his Tuesday morning briefing. “We had a really productive day,” said Jeremy Dietz, operations section chief with Rocky Mountain Complex Incident Management Team 3. In a video posted on Facebook, he gestured to a map that showed the bulk of the fire’s footprint, mostly to the north and east of Ouray. “We got 3% containment yesterday, hoping to build on that.” The fire has grown to more than 31,000 acres, with more than 900 personnel working the blaze. Though Ouray has been spared by the flames, the fire has continued to grow through the high-alpine terrain to its north and east — home to farms, ranches and some rural subdivisions — since June 27.
