| Location description: | Cub Lake (informal name), located in the upper Cook Inlet lowlands of south-central Alaska. The summit of Redoubt Volcano 25 km southwest. Bear Lake is 17 km away. The lake occupies a simple basin at an elevation of 38 m above sea level and has a surface area of 0.5 square km. The maximum depth of the lake is 34 m. The maximum elevation of the drainage basin, which has an area of 10.1 square km, is 1220 m. Three inflow streams enter the lake from the west and south and one outflow drains the lake to the east. Sediment cores recovered from Cub_Lake comprise finely laminated (mm scale) gyttja and 41 tephra layers that are greater than or equal to 1 mm thick. Cores are identified by their core site (e.g., CB-2 and CB-3); surface cores include a letter designation (e.g., CB-2C). The stratigraphies of cores CB-1 and CB-2 are nearly identical and nearly all of the visible tephras can be correlated between the two sites. CB-2, the longer of the two cores, contains 41 tephra layers, which comprise 8% (50.7 cm total) of the length of the core. Ten major tephras and six minor tephras were correlated between BL-3 (from Bear Lake) and CB-2, primarily on the basis of their estimated age, stratigraphic sequence, and color; these tephras were used to form the basic tephrostratigraphic framework and as a basis for correlations of other minor tephras betwen the two lakes. Datum not specified, assumed to be NAD83. |
