AbstractEvidence from aerial photographs, maps, and field checks indicates that 319 glaciers lie in cirques of the Rocky Mountains, south of the United States-Canadian border. On a subcontinental scale, the distribution of glaciers is highly clustered, with larger and denser clusters located in the northern Rocky Mountains. Lesser concentrations of small glaciers occur in the southern Rocky Mountains. The total area of glaciers in the Rocky Mountains of the U.S.A. is 78.9 km2.

Moho Depths

The Southern Rocky Mountains of Colorado, United States, have the highest regional elevation in North America, but present-day crustal thickness (~42–47 km) is no greater than for the adjacent, topographically lower High Plains and Colorado Plateau. The chemistry of continental-arc rocks of the mid-Cenozoic Southern Rocky Mountain volcanic field, calibrated to compositions and Moho depths at young arcs, suggests that paleocrustal thickness may have been 20%–35% greater than at present and elevations accordingly higher. Thick mid-Cenozoic Rocky Mountain crust and high paleo-elevations, comparable to those inferred for the Nevadaplano farther west in the United States from analogous volcanic chemistry, could be consistent with otherwise-perplexing evidence for widespread rapid erosion during volcanism. Variable mid-Cenozoic crustal thickening and uplift could have resulted from composite batholith growth during volcanism, superimposed on prior crustal thickening during early Cenozoic (Laramide) compression. Alternatively, the arc–crustal thickness calibration may be inappropriate for high-potassium continental arcs, in which case other published interpretations using similar methods may also be unreliable.

Eleven Species

AbstractAll Cardiophorus species found in Canada and the United States of America east of the Rocky Mountains are keyed and all but those with the majority of their ranges west of the Rocky Mountains are revised. Eleven species are recognized, three of which are new to science (C. catskillensissp. nov., C. destinensissp. nov., and C. panamapolissp. nov.). Cardiophorus floridae Candèze and C. angustatus Blanchard are synonymized under C. convexus (Say). All 11 are described and taxonomically important characters are presented. Distribution maps are presented for each species. The following lectotypes are designated for species that were described from more than one specimen without former holotype designation: C. angustatus, C. floridae, C. erythropus Erichson, C. gagates Erichson, C. togatus Horn, C. robustus LeConte, C. convexulus LeConte, and C. amictus Melsheimer. The following neotypes were designated to replace destroyed type specimens: C. cardisce (Say) and C. convexus.

High Pollution

The weather over the eastern two-thirds of the United States was monitored, and air pollution potential forecasts were made and disseminated to affected cities. The experiment allowed for air sampling under a variety of synoptic patterns, and the results strengthen the validity of the previously developed criteria as indicators of prolonged periods of two or more days of high air pollution. Other considerations are indicated for the prediction of isolated days (not prolonged periods) of high pollution.
