- •
Pollen records from the Uinta Mountains reveal two major vegetation shifts.
- •
The first shift was Artemisia steppe to spruce parkland during the Younger Dryas.
- •
A shift to lodgepole pine forest occurred earlier at Marsh Lake than at Camp Bog.
- •
Different forest development rates at the two sites were due to local factors.
- •
Fire did not trigger the shift to lodgepole but may have sustained it until now.
