Cougar Mountain Cave is located in Oregon's Fort Rock Basin. In 1958, avocationalist John Cowles excavated most of the cave's deposits and recovered abundant fiber, lithic, wood, and osseous artifacts. A crew from the University of California, Davis returned to the site in 1966 to evaluate the potential for further research, collecting additional lithic and fiber artifacts from disturbed deposits and in situ charcoal from apparently undisturbed deposits. Because Cowles took few notes or photographs, the Cougar Mountain Cave collection—most of which is housed at the Favell Museum in Klamath Falls, Oregon—has largely gone unstudied even though it contains diagnostic artifacts spanning the Holocene and, potentially, the terminal Pleistocene. We recently submitted charcoal and basketry from the site for radiocarbon dating, providing the first reliable sense of when Cougar Mountain Cave was first occupied. Our results indicate at least a Younger Dryas age for initial occupation. The directly dated basketry has provided new information about the age ranges and spatial distributions of diagnostic textile types in the northwestern Great Basin.

Ten objects were used to assess comprehension, production, and imitation of comparative and superlative suffixes in 100 children ranging in age from 2; 6 to 4; 6. The results indicated that comprehension of both suffix forms was similar at each of five age levels studied; although incrementally better comprehension scores occurred with succeeding ages. Virtually all subjects were successful in imitating forms missed during the comprehension task. Analysis revealed that the -er suffix was produced more often than the -est suffix, at the youngest age (2; 6): at succeeding age levels this difference was reversed. Big was the primary lexical unit selected by the subjects for positive and negative polar forms connoting size; little was the second most frequently used adjective form.
