At L’Anse there is an unconformity which we will visit. Unconformities are places where the geological record has a demonstrable gap, where time is unrecorded. There are several kinds of unconformities, but angular unconformities pose some special problems. Geologists start with Steno’s Laws--proposed by Nicolas Steno in the 1600s. To devise claims that illuminate unconformities, geologists pointed to evidence for deep time. The most famous unconformity in geology is at Siccar Point, in Scotland where James Hutton explored deep time implications of earth science in a profound way.
