Juneau Nature - Natural & cultural history of Juneau & Southeast Alaska

Southeast Alaska

Our dynamic home

In 2011, Cathy Pohl and I [RC] received a drive with 22,000 scanned air photos taken by the Navy in 1948. For the first time, cartographers and researchers in Southeast Alaska could efficiently access this extraordinary collection, studying natural and anthropogenic change in photos spanning 60 years.

To celebrate, I created this 35-minute narrated slideshow comparing the 30-or-so Southeast communities, then and now.


We describe the broader context of Southeast Alaska according to biogeographic provinces. On map below, the 3 provinces of CBJ are numbers 5, 6 and 14.


The 22 biogeographic provinces are numbered here from north to south along the mainland, then from N to S through the archipelago. Color ‘families’ group 22 provinces into 5 clusters based upon distinctive mammal assemblages. Blue—mainland. Browns—Chichagof-Baranof. Yellow—Xutsnoowú. Greens—central & inner islands. Pinks—Tàan (POW) & southern outer islands. They’re defined in Carstensen, Schoen & Albert (2009).   Provinces selected for treatment here are those with Juneau’s near-neighbor cities and villages. While the roaded portions of the CBJ (City and Borough of Juneau) are described by watershed in our Juneau section, the more remote portions of our ‘home provinces’ (for example, Tracy Arm in Taku province) are treated here.

3 Glacier Bay  World’s most dramatic Little Ice Age.

4 Chilkat  Our richest rivers. Home of Haines and Skagway.

5 Lynn Canal   Steepest mountains and deepest waters of the Inside Passage.

6 Taku  Corridor to interior.

11 East Chichagof  Hoonah’s province

12 West Baranof   Sitka’s province
