Two lecture rooms are named after him in the Department of Earth Sciences, University of Cambridge.

The archive comprises notebooks, sketchbooks, and photograph albums detailing geological excursions in the U.K from the late nineteenth century. These mostly cover the Isle of Skye, Isle of Arran, Yorkshire (Scarborough), and other Scottish Highlands. There are also notebooks detailing specimens collected (catalogues), lecture note drafts, maps, and some personal records including details of an 80th birthday event.
