Interferogram created from satellite radar data collected on October 7, 2024, and October 2, 2025, over the Yellowstone region by the Sentinel-1 satellite system. Colored fringes indicate a change in distance (called range change) between the satellite and ground surface that is caused by surface deformation during the time spanned.

Rocks, mud, and woody debris deposited by both flood and debris flow processes are visible in this upstream section of watershed burned by the 2024 Elk Fire near Dayton, Wyoming. The coarser material near the far channel edge was carried by a debris flow while the well-sorted finer material in the foreground has properties associated with flood flow.

Plot of temperatures measured by continuous loggers at Guardian Geyser (light red) and Valentine Geyser (dark red) on August 24, 2025. Activity at Guardian Geyser included episodic splashing for a few hours prior to the near-simultaneous eruptions of both geysers just after 6:30 a.m. MDT on this date.  Data collected by Mara Reed, Yellowstone National Park.
