Hauling field gear up Gothic Mountain…
Master chronologies were constructed for each of four Colorado stands of Pinus aristata Engelm. Apishapa Pass, Cochetopa Pass, Mt. Bross-Windy Ridge, and Mt. Goliath stands are located in south, central, north-central, and north Colorado, respectively. The low level of correspondence among the master chronologies prohibit the merging of the four separate chronologies into one. The validity of merging chronologies over extensive geographic areas for dendrochronologic purposes is questioned. Results of this study refute generalizations made in a previous study of the Mt. Goliath bristlecone pine stand. Located in the Mt. Goliath stand is the oldest reported bristlecone pine in Colorado dating back to A.D. 403, 1,570 years. Densewood damage, previously not described, is a distinctive morphologic feature of some growth layers, and is useful as a diagnostic character in dendrochronologic analysis. Of the 29 previously unreported sites for P. aristata in Colorado located during the field reconnaissance, one significant cluster of stands on the east side of the San Juan Mountains complex near the Colorado-New Mexico border is the first reported for the San Juan Mountains proper.
