    Wildfire activity in northern Rocky Mountain subalpine forests still within millennial-scale range of variability by Kyra Clark-Wolf, Philip E Higuera, Bryan N Shuman, Kendra K McLauchlan

    Published 2023-01-01
    “…Here we present a network of 12 fire-history records derived from macroscopic charcoal preserved in sediments of small subalpine lakes within a c. 10 000 km ^2 landscape in the U.S. northern Rocky Mountains (Northern Rockies). We used this network to characterize landscape-scale burning over the past 2500 yr, and to evaluate the precedence of widespread regional burning experienced in the early 20th and 21st centuries. …”
