GROUND OBSERVATIONS DURING FROSTFIRE
| The team on nearby Caribou Peak, about 2km across the valley from the prescribed burn, operated a color videocamera, a second infrared videocamera, a spectrometer, and a black and white telephoto lens camera with a filter to capture images of carbon flame emission. All these instruments, three VCRs, and three laptops were powered by a purring portable Honda generator. |

| The Inframetrics Thermcam records data showing the fire's emissions in the infrared during blacklining. A flame filter and a CO2 filter were used to isolate emissions in narrow wavelength bands. | Alaska Fire Service escort Glen Claypoole demonstrates how to apply MRE (Meals Ready to Eat) | Fires smoldering in the valley overnight turned into racing crownfires the next morning. |
