Along the Fish Lake Road, McIntyre Creek has steep banks and a narrow creek bed. These distinctive features are characteristic of a glacial meltwater channel developed in bedrock. Upstream, the valley cross-sectional shape is wider and shallower because the stream eroded less resistant glacial sediments.
At the start of the Fish Lake Road, cliffs of light-coloured rock look remarkably crumbly and delicate. This is a rock texture known as grus, which is a term to describe granitic rocks that have experienced significant weathering by interaction with hydrothermal fluids.

The Pueblo mine disaster was the trigger for the establishment of worker's compensation legislation in the territory. Shortly after the disaster, the Workmen's Compensation Ordinance received assent in the territorial legislature.
