Yellowstone National Park has closed the road between West Thumb and Old Faithful because of smoke from the Lone Star Fire.
Originally reported Saturday, the lightning-caused fire is about 3 miles south of Old Faithful and is being calculated at 300 acres, the same size reported Saturday night.
The closure was originally only from Kepler Cascades to West Thumb but was expanded Monday. Old Faithful is currently only accessible from the north.
Yellowstone officials said in a press release that the fire is not burning toward Old Faithful, but that employees were making preparations in case the fire changes direction. Additional crews and resources were expected to arrive Monday.
Backcountry closures are in place in the Shoshone and Lewis lakes area, and the Lone Star Trail is closed. Check Yellowstone's Backcountry Situation Report for the most recent updates.
Lightning has been prevalent throughout the park this week, and fire danger is very high. Campfires are not allowed in the backcountry.
Across the region, fire danger is elevated and fire restrictions have been put into place. On the Bridger-Teton National Forest, fires are only allowed in developed campgrounds and picnic areas. In Grand Teton National Park, fires are limited to designated, installed fire rings or grills.
In Sublette County and on area Bureau of Land Management property, all outdoor fires are prohibited except campfires within established developed rings, charcoal grills and trash or refuse fires within containers with spark arresters. Fireworks and explosives are also banned on area BLM lands.
