The Jack Creek Fire was started by a lightning strike on August 11, 2017, about 15 miles southwest of Leavenworth, Washington in the Alpine Lakes Wilderness in the Okanogan-Wenatchee National Forest.[1] The lightning was caused by a cold frontal passage that tracked through the area.[2] It remained dormant for weeks, only growing to 7acres before it burned into receptive fuels and grew.[1] [2]
By September 3, the fire had grown to approximately 700acres due to warm temperatures and low humidity. On September 11, the fire made a run, growing to 1600acres by expanding into the Stuart Lake and Eightmile drainages.[2]
The fire caused the United States Forest Service to close a number of areas in the impacted recreational areas, including Colchuck Lake, Meadow Creek, Snowwall, Blackjack Ridge, Jack Ridge, Eightmile, Stuart Lake, Van Epps and Trout Lake trails. Select trails reopened on September 26. By that day, the fire had grown to 3724acres and as zero percent contained.[3] By the end of the month, the fire burned a total of 4606acres.[2]
In October 2017, the Central Washington Burned Area Emergency Response completed an assessment of the burned area, and requested $12,385 for emergency treatments, primarily due to soil erosion and post-fire flooding concerns. An estimated four miles of trails along Jack Creek, Van Epps and Eightmile drainages have increased threats of rockfalls and flooding.[2]
