How streams & rivers shape land & interact with forests
These illustrations were created for different projects. Upper one was part of a middleschool geology curriculum. Lower one was commissioned by Alaska Dept of Fish & Game for a publication on salmon. I’d been working on Jordan Creek [no Lingít name?], behind Sítʼ Eetí Shaanáx (Glacier Valley Elementary), and was thinking about that dynamic-&-youthful system when laying out the alternating pools and riffles so important to spawning and rearing habitat. Only later did I notice how the snakey meanders in the 2 block diagrams mirrored each other.
I was wrong. For example, I could find nothing on why exceptionally large trees cluster where streams approach the heads of lakes. Maybe it’s because so little undeveloped alluvial surface remains throughout the world. I guess it’s up to us Southeast Alaskans!
