Abstract

Pollen and spore assemblages from the Tertiary coal-bearing Chuckanut and Huntingdon Formations were studied to determine the existence and location of the southern boundary of the Bellingham Basin. Ages of deposition were determined for each formation based on the flora recovered. The age of the Chuckanut Formation ranges from Middle Paleocene at its base to Late Eocene at its top. The age of the Huntingdon in northwestern Washington is Late Eocene to perhaps Earliest Oligocene. From the evidence of palynomorph ranges, no definite age breaks were found within the Chuckanut Formation, or between the Chuckanut and Huntingdon Formations. The structure of Squalicum Mountain, located near the southern boundary of the Bellingham Basin, was determined by taking numerous strikes and dips (Pevear and Reinink-Smith, unpublished data, 1980; Patrick, unpublished data, 1981). These data suggest that there is not a major angular unconformity at the southern boundary of the Bellingham Basin as previously reported. The data obtained also show that structurally, palynologically, and lithologically the Huntingdon Formation south of the Nooksack River is indistinguishable from the top of the Chuckanut Formation; therefore all of the rocks formerly mapped as Huntingdon Formation in this area should be included in the Chuckanut Formation.
