Mosquito Fire – September 15, 2022

Mosquito Fire – September 15, 2022

Intro & Livestream: Zeke Lunder
Maps & Intel: Ryan Cowper Stephens

September 15 at 7am – Fire behavior was pretty subdued yesterday under smoke and mild winds. We took a trip out to the north end of the fire and connected with the Division Supervisor working on a strategy for areas burned in the 2013 American Fire. We also ran into the Tahoe National Forest Fire Management Officer and his fuels management leadership.

On Foresthill Road, above the town of Foresthill. Water tenders have been applying retardant along the road corridor to prevent spot fires if the road needs to be used as a contingency line.

Our livestream from last night is based on the intel we gathered in the field. There is an extended Q&A on forestry, what it will take to expend the use of prescribed fire, and how fuel and weather conditions are creating problems for firefighters working to contain the spread of the fire into the American Fire scar.

The fire did not spread much on the west, yesterday. We’ll have updated maps and forecasts later today. For now, here are maps from yesterday.

Mosquito Fire Progression Map


Looking southeast over Foresthill. The fire made a big push, spotting over the American River and running nearly two miles, all the way up the canyon to Foresthill Road, east of Sierra View Lane. Fire appears to have crossed Sierra View Lane between Foresthill Road and Patent Road, and is seen on the map in the trees behind Foresthill Divide School.


Another look at the spot fire run yesterday. Spot is seen in dark Red on the north side of the American River.


Firing operation off Foresthill Road, all the way down to Deadwood Road. It appears to be holding as of 6am this morning.


Fire continued marching east yesterday. A firing operation is seen on the left side of the map off Foresthill Road.


Looking east up the Middle Fork of the American River, and over Cuckoo Ridge, Peavine Ridge, Tanners Point and Lynchburg Hill. Firing operations seen along Peavine Point Road on the far right side of the map.


Looking southeast at the Interbay Dam and associated power lines.



Looking west. Lots of place names to help identify precise location of the fire. Spot fires seen around power lines near Brushy Canyon. Fire ran over two miles east up Long Canyon.
