" claire is a soil scientist with the u-s forest service. she and the rest of the burned area emergency team are examining areas at the highest risk for erosion...and landslides. we watched her analyze how well water soaks into the ground. if it doesn't...the soil is called "hydrophobic" ...or "scared of water." "you can kind of see in this higher stuff the water go straight in so we're not having hydrophobic conditions but down here at this mineral level i'm getting that little drop of water that is not infiltrating. when it with in this general area and see if it's continuous and we also like to test how deep that level goes." the less water it absorbs...the higher the risk for runoff. along with the soil scientists, there are archeologists, engineers and hydrologists on the team spread around these woods...trying to find the areas most at risk when the heavy rains come. a main focus: roads and trails. claire says, "we work on culvert crossings so where ever culverts go under the road, we're looking at mostly keeping those stable." if they find a road that could be at risk ...they enhance the culvert. this allows high waters to rush into the culvert from the top...instead of overtaking the road. they may also take down trees if needed ...and try to guess how well the area will bounce back. rachel says, "one scientist told me this is a unique spot because behind me you burn scar from this year's columbus fire. this is important because it helps them see how the area will recover. on the columbus fire burn scar, rachel tiede, nw12. the "baer" team will
