Our passion for history has driven the search for and mapping of more than 1,000 wrecks and underwater objects over the last decade.


TBF-1 Avenger

Wreck of the TBF-1 Avenger in Lake Washington, Seattle.  The image shows the debris field stretching from the lower right to upper left of the image.  Swath width 200 meters.


Antlers Lodge Lake Cushman

While mapping the old lake shoreline as a means to finding the location of the historic Antlers Lodge in Lake Cushman we followed a logging railroad 200' underwater in standing timber.  This image shows a train trestle with standing timber on both ends.  Depth at the train trestle is 196' fresh water.


Search for a Lost Navy A-6 Intruder

The search for and eventual discovery of a lost Navy A-6 Intruder in the San Juan Islands, Washington required the survey of more than 20 square miles.  The entire search area is a high current area with many underwater obstructions, mid-water currents, and down swells.

An effort is underway to mosaic Lake Washington near Seattle.  We have mapped most of this lake previously using a low resolution search pattern and are now attempting to image at 10 cm resolution for the entire lake.
