Fixed link to glacial erratic field trips

Several alert readers let me know that the link to the field trips to glacial erratics in the Salish Lowland was broken. So, I have fixed it. Go to the ‘Field Trips’ tab at the top of this page, scroll down to the blue Glacial erratics text, and try out the link. Unfortunately, the online inventory of glacial erratics maintained by UW students, reached by a link on my erratics page, is an uncompleted website, a student project, and does not actually take you to an inventory or map or photo. Dang.


Just for grins- here is a large erratic not previously visited on this website. Any one know where it is? Hint- north of Seattle, south of Bellingham. Its a pretty big rock. Shows well in Google Earth.

  1. I suppose “Texas” would be too obscure of a hint.  I enjoy your site! Chuck Guilford

  2. I recognized this instantly! On March Point, Fidalgo Island. I’ve passed it many times and I always wonder about it. It’s too bad that it’s fenced off to that degree.

  3. West side of March Point, Anacortes!

    The snow in the shade threw me off, but the Tommy Thompson Trail Trestle in the background was the clincher for me.

    I’ve biked over the trestle many times en route to the SJIs but I did not know there was a big rock over there! We will have to detour a little further north next time. I didn’t realize you could drive/bike around the entire peninsula on March Point Road… I figured there would be a refinery-related gate somewhere preventing such a tour. It looks like combined with North Texas Road March Point Road would make a good loop tour of tanks and pipes and flaming stacks to one side and tidal, island and mountain views to the other.

    I fondly remember well a field trip with you in 2010 or 2011 to various Fidalgo Island locales including Washington Park (Fidalgo Ophiolite), Mt. Erie and Cap Sante Park (for the spectacular views and glacial striations! Can’t remember the particulars of the bedrock… more turbidities perhaps? Maybe you can see this erratic from Cap Sante?). A MBVRC fundraiser I think.

    I just realized that this erratic on N Texas Rd. is VISIBLE in the background of this photo from August 2019! HA!

    Thanks for sharing this Dave! I’ve always appreciated and admired your work sharing the wonders and thrills of earth science.

    Warmly, Jonathan

    • Thanks, Jonathan,and greetings. Those MBVRC field trips were a good time. Alas, we closed down the non-profit a couple years ago. The website is still up. Dave Tucker

  4. Very nice. I recognized the background, vaguely remembered seeing the erratic, found it in Google maps “Satellite” view, and came here intending to say “Texas Rd.”

    I don’t think “Texas” was an obscure hint at all – it would have given it away with just a glance at the picture.

    I guess the “Tommy Thompson Trestle” is that thing I know of as the “old Great Northern trestle.” I’ve got pictures I took of GN locomotives (or maybe the same locomotive) sitting by the Anacortes train station, ca 1966. A while ago now. Even then, I was sad that the railway no longer ran on the line around past the ferry dock to the old blimp hangers by Washington Park, which I remembered from when I was a kid. Now I’m glad to have the memories.

    I always enjoy this blog, and this was an especially happy entry.

    Thank you.

  5. N Texas road, March Pt, looking west. Just dumb luck that I live a few miles from there.
