Back in this country, firefighters in Northern California made more progress today against the massive Caldor Fire raging near the Lake Tahoe resort area.The flames are now 20 percent contained, after burning more than 204,000 acres since mid-August. Stephanie Sy has the latest.Plumes of black smoke rose above the historic Echo Summit mountain pass early this morning, signs that the Caldor Fire is creeping closer to South Lake Tahoe, the most populous city on the lake.Nearly 4,000 firefighters battling the raging inferno made some progress today.The fire has already destroyed hundreds of structures.We have been resource-starved here at times.We're continuing to get more people sent to us, but it's still not enough, as this fire is shown to be a huge challenge for everyone involved.Fuel load is extreme out in these areas. Everything is easily ignitable.And the vegetation is very thick and dense and the areas are sometimes inaccessible.Thousands of members of California's National Guard have also been deployed to assist with the fire response and evacuations.For days, erratic winds and low humidity have spread spot fires, with embers flying and spreading the flames.Those ember casts that it throws out are going over a mile in distance.So that's what's propagating the spread of the fire right now, is that long-range downwind spotting of that ember cast.
