Wreck of The City of Kingston, Tacoma's Commencement Bay

CityofKingston.gifThis image is believed to be the wreck of the steamer City of Kingston.  The City of Kingston sank after colliding with the steamship Glenogle while negotiating a fog bank the morning of April 23, 1899.

The Kingston was heading into Commencement Bay Tacoma Washington after traveling from Victoria.  The Glenogle was leaving the bay for Hong-kong.

The Glenogle made it back to the port with minimal damage.

Thanks to Pete Dartnell of the USGS for making this data set available and to John Sharps of JAWS Marine for use of location and historical research.

Side scan mosaic of the Olympic Coast National Marine Sanctuary in Washington State

Olympic-NMS---Sidescan.gifThis image was generated by compiling data sets from NOAA’s mapping efforts in the Olympic Coast National Marine Sanctuary. The data sets are exceptionally detailed and can be used to view geology and objects as small as 5’ in length.

ESRI’s ArcGIS software is being used to view data sets.  This same technique is being used to compile datasets of the Puget Sound and Lake Washington.  Our team is rapidly compiling data from several organizations who have generously made their work available and integrating this data with our own side scan mapping.

Side Scan Imagery of Cove 2 - West Seattle

Cove-2-3-Labeled-2.gif

 

This image is a side scan image taken by Shaun Gardner and Puget Sound Divers of Cove 2 in West Seattle.  This is a very popular dive site.

A Burton Side scan unit was utilized and deployed from the boat of Seattle's NAUI Technical Diving Instructor Scott Christopher.

You will note that the image shows the I-Beams, the Row Boat and log holding it in place as well as a plastic 55 gallon drum between the boat and the I-Beams.

Of interest to divers will be the angle of the log piles.  These piles are commonly used for navigation at depth between the boundary line separating the fishing area  from the diving area and the popular I-Beams.

If you look carefully along the edge of "Log Set 1" you will see the rope boundary line and the dots represent milk jugs and soda bottle floats.  You can actually make out the line as it arcs over to cove three. 

To assist with orientation: the solid black area is the bay side (Right side of Image) and the shore is to the left side of the image.

Divers wishing a higher resolution image should simply chose the "Contact the Team" Link in the navigation bar.  Give us a couple of days and we will send you a copy.  Furthermore, divers wishing to expand the mapping of local dive sites are encouraged to contact us and we will publish your maps, images, pictures, videos, etc.  Any diver wishing to contribute to the overall diving community in this way will be given full credit for their hard work.

Father's Day Dive on the MT 6

Sunday, Peo Orvendal, Mark Tourtellot, Walter Jacard and Scott Christopher joined Mike Ferguson at Porthole Charters for a dive on the MT 6 (the Tacoma). This vessel rests upright at 200 fsw in Elliot Bay.

MT6-3.gifThe plan:

Scooter the wreck for 25 – 30 min

Deco:

40-50 min

 

The Teams:

Peo and Mark

Walter and I

Support:

Larry Cleeton

Captain:

Mike at Porthole

We all descended to 195 fsw together. There was no need to search for the wreck as Mike and Larry dropped the line in the perfect spot, which of course is close enough to see the wreck, yet far enough away as to cause zero damage to the site. Mark and Peo broke off to the starboard side, Walter and I crossed the ship and continued counter clockwise around it. Scootering this wreck allows you to see every inch of it. Visibility was stellar on the bottom. This is truly one of the best wrecks in our area. After circling the wreck a few times Walter and I decided to do a little penetration though an opening in the side of the wreck. Walter tied in a primary and secondary tie and we proceeded inside. There was just as much life on the inside of the wreck as the outside. We reached a point in the penetration where it would have been difficult to continue forward carrying deco bottles and scooters, so Walter signaled to exit. We exited the wreck, removed the ties, and continued to explore the exterior of site. At 30 minutes, we meet up with Mark and Peo and started the journey back to daylight. Larry met us about half way up and made certain we were squared away for the remainder of deco. The deco was pleasant, as the current was very light, the water was a few degrees warmer than the bottom, and the visibility was still great. We saw all the usually PNW life on the wreck. We observed lots of Rock Fish, a giant Ling Cod, and tons on invertebrate life. We all left the Mariana to spend the rest of the day with our families. Thanks to Mike for being a great captain and host, Larry for an awesome support role, and Mark, Peo, and Walter for being great teammates. Next up the AJ Fuller at 240 fsw in a few weeks.

 

Side Scan Imagery of the AJ Fuller in Elliott Bay Seattle

The AJ Fuller is a large 229' three masting sailing ship that sank in Elliott bay in 1918.  Do to the vessel's size it is difficult to image.  Even on a 500' scan the ship takes up most of the screen.

AJ Fuller - The square object at the bow is actually artifact created by moving the side scan units angle around the bow.  We needed to change course to avoid ferry traffic.

Note the barge to the left of the Fuller's stern.

This image is the Fuller taken from the side.  The hope was to cast shadowing of any deck structure.  As you can see little shadowing is evident.

Side Scan Imagery of the MT 6 (Former Ferry Tacoma) in Elliott Bay

Below are two side scan images of the MT 6 resting in 200fsw just of Salty's in Elliott Bay Seattle.  This wood barge is a fun and impressive dive.  Protected from current by its location deep in the bay it can be dove most days regardless of slack timing.  Considerations for this dive include the need for Coast Guard Permission and the fact that the Duwamish River dumps into Elliott Bay very close to this site. 

MT6-1.gifThis scan gives the best representation of the barge's shape.

 

John Sharps of Jaws Marine has an excellent accounting of the MT 6's history.

This images was taken aiming the side scan unit down over top of the barge.  Note the flat deck is intact in many areas.

Wreck of the Falcon

Today Puget Sound divers Bob and I explored one of the old Mosquito fleet ships that was sunk in about 200ft of water. Located north of 520 the weather conditions were great. After a short descent the wreck was quickly located and the down line tied in. At a length of about 80ft the all wood boat is in good condition upright on the bottom with a list to the port side. When approaching from the bow one should use caution that they do not swim into an overhead environment. A roof extends forward and with limited viz, which is common, you could be far inside before you noticed.

Falcon.gif

This side scan image shows the bench on the back deck and raised superstructure.  In the shadow you can see the open roof extending forward.  This raised deck structure has cast shadows over the lower edge of the hull preventing imagery of the portions of the bow.

We spent twenty five minutes on the wreck before returning to the surface with decompression stops and gasses consisting of 50% and 100%. This is a wonderful wreck and worth future dives.
