The fire is showing minimal fire behavior and should be fully contained as of September 2.ġkm (203.8 KB), 500m (504.9 KB), 250m (304.Following an unprecedented outburst of dry lightning in August 2020, wildfires ignited across the state of California. It has burned 68,637 acres and as of the last incident report on August 22 was 82 percent contained. The burn scar to the east of the Caldor Fire is from the Tamarack Fire, which ignited on July 4 from lightening. The cause of this fire, which ignited on August 14, is under investigation. Reports on September 1 suggest that firefighters have made progress in stalling the fire’s approach to the town but are still fighting gusty winds and extremely dry conditions. According to local news reports, on August 30 about 22,000 residents of South Lake Tahoe jammed the main roads out of town after they were ordered to evacuate.

Firefighters continue to try to turn the fire from communities on the southern end of Lake Tahoe as the fire moves closer to the resort area. The blue lake to the northeast of the Caldor Fire is Lake Tahoe. Combined with typical smoke-as in this image-such hot spots mark actively burning fire. These are areas where the thermal bands on the MODIS instrument have detected high temperatures. At the edge of the Caldor fire, bright orange “hot spots” can be seen. Some areas of vegetation remain within the burn scar, indicating that these spots were at least partially spared from the flames. In this image, most of the freshly-burned land appears brick red and stands out in dramatic contrast against the green vegetation. Burn scars can be colored black, brown, or brick red, depending on the type of vegetation burned, the completeness of the burn, the amount of residue that remains, and the age of the burn. Here, vegetation appears bright green, open land appears in shades of tan, and water appears blue. This type of image uses short-wave infrared, near-infrared, and red wavelengths (Bands 7,2,1) to contrast burn scars from vegetation. On August 28, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a false-color image highlighting the massive burn scar of the Caldor Fire. The Caldor Fire, with 207,931 acres affected in El Dorado County, ranks as number 15 for size. The Dixie Fire, which started in July and continues to burn in Butte, Plumas, Lassen, and Tehama counties, has burnt 844,081 acres, to make it the second-largest fire in the state’s history.

As of September 1, both fires have also made the top-twenty list of all-time largest California wildfires.

According to news reports, both the Dixie Fire and the Caldor Fire have become the first two fires known to have crossed the ridge of the Sierra Nevada, burning from one side to the other. Two of the California blazes have burned their way into the history books. The 5-year average is 6,170 fires and 782011 acres. According to CAL FIRE, as of August 30, 6,983 fires in California have scorched 1,887,773 acres. While this is close to the ten-year average in the U.S., California’s statistics are beating the 5-year average in that state. On August 31, the National Interagency Fire Center reported that in the first eight months of this year, 42,647 fires had seared 4,879,574 acres across the county. The 2021 fire season has proven excruciating for much of the United States, especially in California.
