Researchers from the U.S. Geological Survey collect samples of ash and burned soil after the Fourmile Canyon fire. Photo credit: Gregg Swayze, USGS   October is Wildfire Awareness Month, so on today's show we look back at the Fourmile Canyon wildfire and hear from local researchers about some of the scientific opportunities that the fire afforded over the last year. Jim Roberts, an atmospheric chemist at the National Oceanic and Atmospheric Administration, tells us about some of the unexpected compounds that have recently been found in the smoke of wildfires. And Deborah Martin, a hydrologist with the U.S. Geological Survey, describes how post-fire runoff from rainstorms affects the forest landscape.
