McCargoe Cove Archeological Survey Dive, Isle Royale
The goal of this project will be to
accomplish an underwater archeological survey in McCargoe Cove at the
Isle Royale national Park. Divers will be looking for and documenting
artifacts from a long range of history, from pre-historic copper mining,
the fur trade, the War of 1812, fishing, and 19th
century copper mining. Depths will range from very shallow work down
to about 40 feet. Skills used will be underwater navigation,
photography and tri-lateralization techniques.
We will be using the Amygdaloid Ranger
Station as a base of operations so we will have the use of a dock, can
set up tents, will have a water supply and a fire pit. In addition to
diving this is a beautiful place for hiking and exploring.

Please check back from time to time to catch up on the latest changes
and advancements to the project. This is also the first stage of the
project. We will continue this project for the next few years until
completed. So please register early.
PLEASE NOTE: Because of the
intensity, distance and the remote location of this project, a slight
$80.00 fee is asked to pay to cover mostly the food and some fuel for
the boats. (Please pay by credit card)
Please print, read and sign the GLSPS Master Liability and Waiver Forms and bring them with you and hand into the Project Leader or a GLSPS Representative. Please note:
Please prepare your forms before you arrive at the Marina / or boat
(R/V Preservation). This will help speed up the process at the dock
before we depart.

April 5, 2011
First blast email sent to GLSPS Members to Announce the GLSPS McCargoe Cove Project that was approved by the Board of Directors. The Project will be Scheduled for August 5 -10 , 2011. On the events calendar on this website.
Email blast sent out to Members about why the project is needed.
Email blast sent to members to indicate what we are going to do, requirements for the project and gear / equipment needed.
Email sent to attendees of the Project one week before on a final plan as to what where and how we are performing this project.
A second email sent the same day to indicate the legalities of the project with a link to the Liability and Waiver Release Forms.
Email sent to attendees about a piece of equipment built by Todd Lindahl and Don Minuay to aid in the underwater documentation of the artifacts. (See Attached picture below)
E-mail sent to 2012 attendees updating plans to use the PRESERVATION and to confirm the dates for the project

An email was sent to attendees to make sure all divers clean their gear thoroughly to prevent the introduction of invasive species into McCargoe Cove.
An email sent to attendees to bring an extra tank if they had one available. Extra tanks would cut down on the noise caused by the scuba compressor use on the boat near the Island. A noise restriction is enforced on the docks at Isle Royale National Park.

McCargoe Cove Survey Project began today. Loaded up the two boats, the
R/V Preservation and The R/V Arctic Fox with dive and documentation equipment, cameras, remote sensing equipment, and other provisions such as food and drink for the crew. We then cruised 6 hours over to the North end of the Island to McCargoe Cove. Docked at the teams base of operations, the Amygdaloid Island Ranger Station for permitting and registration. An orientation was presented by the Isle Royale National Park Cultural Resource Manager Seth DePasqual and project leader Randolph Beebe. The day ended with Bob Nelson cooking a great meal and an evening by the campfire discussing the next days dive plan.
August 6, 2011
There were two separate missions planned on this date and the group was split into two separate teams. The
R/V Preservation departed the dock at Amygdaloid Ranger Station early in the morning with 5 out of the 6 of the available divers to begin a systematic series of dives covering the bottom of McCargoe Cove locating and document any cultural artifacts that were found. It was decided that due to previous historic activity and water visibility the teams would work from the North end of the cove and move in a Southerly direction
While the dive teams were busy with the underwater survey the second team, using WolfsHead Research's boat the
R/V Arctic Fox and Imagenex side-scan sonar, surveyed the entirety of the cove using both the 300khz and 800khz resolutions. All of this data was recorded for future ground-truthing dives to identify any anomalies that were found.
On these two dates the dive team was split evenly between the two boats and a series of dives were made systematically surveying the Cove bottom. It was during these dives that the methodology and procedures of the survey were fine tuned using input from all of the GLSPS members and the National Park Service. Once the crews became comfortable with the survey techniques progress sped up considerably and quality data was being collected on artifacts by combining diver description, U/W photos and GPS coordinates.
August 9, 2011
On this, the last day slated for underwater work, the divers were once again divided. The divers on the
R/V Preservation continued the survey work and the R/V Arctic Fox, with 3 divers, conducted follow up dives on selected side-scan sonar anomalies. The teams were once again combined for follow-up dive briefings and evening relaxation at Amygdaliod Island
August 10, 2011
This was the planned date to cruise back to Grand Portage, but due to high winds out of the NW it was decided to postpone the crossing for a day. The day was spent organizing paperwork and data and exploring Amygdaliod Island.
August 11, 2011
After an early morning departure the
R/V Preservation and the R/V Arctic Fox had an enjoyable cruise back to Grand Portage in calm seas for the end of the McCargoe Cove Survey project. The team had a productive and immensely enjoyable time working on this interesting project in one of the most beautiful and interesting places on the Island.
Boats tied up for the night
