I visited to Fort Collins to help celebrate the 50th anniversary of the CSU Department of Atmospheric Sciences. A great celebration and an opportunity to see colleagues I haven't seen in many years.

On Saturday I drove through a section of the Cache La Poudre River to see some of the burnt scares from the High Park fire. The fire started on June 9 by a lightning strike and burned across 87,284 acres by early July, taking 259 homes. One person has died in the fire. It is the second-largest fire in Colorado's history and has cost about $30 million to fightHigh Park Fire impact on the Cache La Poudre River: A view of the Cache La Poudre River on July 14, 2012

A recent rain washed the ash into the river, which now runs gun-powder black, as you can see in the photo. This is black color is consistent with the name Cache La Poudre. I have to wonder how this sediment will impact the fish in the water. This is an excellent river for trout.

Notice the burnt trees along the ridge line in the photo. Also notice the dead pine trees in the photo; a result of the pine beetle. The mountain pine beetles inhabit ponderosa, lodgepole, Scotch and limber pine trees and play an important role in the life of a forest. The black beetle attacks old or weakened trees which helps development of a younger forest. However, unusual hot, dry summers and mild winters have led to an epidemic. It would seem logical that these beetle damaged trees would increase fire risks as dead trees are flammable and likely to catch fire. But this might not be the case, indeed the dead trees may inhibit the spread of fires. The Yellowstone wildfire of 1988 provided forest ecologists with a method. Large crown fires can swept quickly through the forest spreading from tree tops. In the 1988 fire there were many trees killed and their needles burned off, but the standing dead tree trunks remained. New wildfires tend to slow and sometimes burn out when they reach standing dead forest. An interesting research topic!
