The long hike to Helen Lake (Banff National Park, Alberta) is worth it, not only for the mass wasting and glacial geomorphology, but also for the stromatolites.
Aaron Barth and I hike up there last summer to GigaPan them (GigaPan images in a separate post, here).
Just another day in the office…
As a “Christmas gift,” enjoy these images… some of the loveliest stromatolites I’ve ever seen:
Marvellous! Still in their colonial aspect, it would appear.
These stromatolites are dead, right?
Yes, for half a billion years and counting…
