Two different storms started the Black Hills and Fish Lakes Fires on the Tetlin NWR. The Black Hills fire was started by lightning on July 16th. The Fish Lake Fire was first sighted on July 29th, probably resulting from lighting on July 21st. These two fires were authorized for Wildland Fire Use, and named the Black Hills Complex. The Black Hills fire was approximately 42,000 acres on August 18thmaking it the largest fire ever to burn on the Tetlin National Wildlife Refuge. Tetlin NWR and Wrangell St. Elias National Park and Preserve managers agreed to a joint Maximum Manageable Area of 998,857 acres (Figure 1). The fire crossed on to the Preserve on August 20, 2003. This document will summarize activities taken on the complex relative to fire behavior and the Fire Behavior Group, including an assessment of existing fuels,seasonal severity, observed burning conditions, and the probability of fire spread to various points of concern associated with individual fires.
