2026 Update

In early 2026 Avenza announced with no notice that they are ceasing to accept new maps to the map store. We are working to come up with a new solution for distributing our maps for the 2027 season. In the mean time we are providing maps for 2026 free of charge as we transition. These PDF files can still be imported into Avenza if you purchase their $35 “Plus” account.

Support the Maps

A few people have asked me about donations. Donations are completely optional, but during this time of transition I will be investing a significant amount of time into developing a new solution this winter. Your donation will help keep the coffee hot while I smash my face into the keyboard until a new app comes out.

Thank you to everyone who has supported me thus far.

Commercial Fishing Maps

Pinnacle Geo produces marine navigation maps for the Copper River Delta and surrounding areas. These maps are built from imagery captured at low tide to clearly reveal shallow channels, bars, and flats that shift from year to year. Updated maps with new imagery are released every spring to reflect the latest channel changes.
