Collins Gulch, Colorado, USA - CO596 Additional information Connie A. Woodhouse Mark Losleben Purpose of Collection: Climatology Detrend method: Negative exponential or linear regression of any slope, or 2/3-length spline. Detrending was done interactively, and if a negative exponential or lenear regression fit poorly, a 2/3-length spline was used. Cores are stored at: Institute of Arctic and Alpine Research, University of Colorado Reference: Woodhouse, Connie A.; Gray, Stephen T.; Meko, David M. 2006.
