Coordinator notes: This caterpillar is Orgyia pseudotsugata, which has brown or golden tipped dorsal tufts. It is a pine forest defoliator (ie. pest) that has periodic outbreaks, including a major one in Colorado in 2015 (I saw them all over the Meadows Group campground around this same date). Your yard probably has ponderosa or fir tree(s), their host plant.
