The Mesozoic sequence west of Harrison Lake is the most complete and best understood section of Middle Triassic (Ladinian) to Lower Cretaceous (Albian) rocks of the western part of the Coast Belt in British Columbia. This detailed study of the lithostratigraphy and biostratigraphy of the strata permits a reconstruction of much of the history of sedimentation, volcanism, plutonism, uplift and erosion during Mesozoic time in the Coast Mountains, an area commonly devoid of stratigraphic sections with reliable fossil control. In this bulletin, several fossil groups are used to date the various lithological units that can be traced into the plutonic complex. The studies in which this report is based were carried out during a three month period in 1985
