Bighorn Mountains Dendrochronology

Inferno Canyon, MT

Inferno Canyon is the northernmost site sampled in 1998. It is a shallow canyon with Utah Juniper common on most surfaces, and forests of limber pine and Douglas fir on some north-facing slopes, especially at the base of rimrock. We found one ponderosa pine with several apparent offspring. Ring width series from cores of living limber pines and cross sections of dead limber pines were included in a chronology which is strongly correlated with climatic records.
