MLP is an interdisciplinary collaboration focused on exploring change in Canada's mountain environments. Utilizing over 140,000 images taken by land surveyors from 1861 - 1953, MLP researchers seek to re-photograph these images as accurately as possible and make the resulting image pairs available for further investigation. For more information on the project check out www.mountainlegacy.ca

Explorer is a map-based tool designed to allow anyone with a modern web browser to investigate the MLP collection. Clicking on a map point will show historic and modern comparative photographs. More images are added as they are completed, so visit often to see what's new!

If you intend to use images in publications or other media, including websites, please drop us a note to let us know about this--it's wonderful to see the images used and enjoyed.
