A Marl Bog


Marl is common in post glacial lake bed sediments often found underlying peat bogs.  Marls are calcium carbonate or lime rich mud which contain variable amounts of clays and calcite or aragonite.  The term is most often used to describe lake sediments, but is also used for marine deposits.  The term marl is widely used in North American geology, while the term seekreide is used in European references.

This is a remembrance post from Anne’s and mine Great Adventure.  The day was July 15, 1982, a Thursday.   We are on just our second day from out from the Cabin.  We are headed down state to the planet, which was not called that then.  We had camped the night before at the Foley Creek National Forest Service campground, just north of St. Ignace.  Yesterday we had gotten 44 miles, are first serious ride in over two weeks.  Here is the story:

Today is a tourist day.  We take the ferry from St. Ignace to Mackinac Island and play on the island all day.  First we shop and Mark discovers why tourists are called “Fudgies”.  Then we ride over the island, by Skull Cave, the battlefield, etc.  We ride back around the east half of the island and then do the fort.  We ride to the Grand Hotel, but the admission fee deters us.  Pizza before the ferry ride to Mackinac City fills us.  This is a good thing since we end up having to backtrack five miles from our planed destination at the Wilderness State Park (home of the marl bogs) to a KOA campground.

Anne always hated KOA campgrounds, but I secretively like them.  I’ve always enjoyed that rustic experience of setting your tent up on freshly mowed grass.  The back story was that before we set out from the Cabin, Anne told me that she had always assumed that I would want to end the bike trip there.  Frankly, this surprised me.  I always intended to go on.  Maybe it was the Michener novels? 

I always set the pace.  Wait, I was the accelerator and Anne was the brake.  I always tried to wait for her at the top of the hill.  Sometimes I would launch down the hill just before she could catch her breath.  That trick worked maybe once.  Usually, I pulled out the current Michener novel and read as she approached and then rested.  I read more than a few of his books.  Most times when Anne was ready to go so was I, but sometimes James A. had me in a headlock and Anne would just set off ahead.  I liked having a lot of reading material in one volume. 

When we left the Cabin we had only ridden 60% of the mileage that we eventually obtain, some 5,000 miles in total.  We only got 24 miles that day.  In the week to come, as we eventually cranked up to speed, we obtained our adventures one and only century, a hundred miles in one day.  We did this on our arrival into Ann Arbor.  There we partied with the honeymooners, Anne and Bill and our friends Alice and Chris, bumming rides or just biking around town.

My spovely louse has just researched the Great Adventure, i.e. the diary she kept and determined that these photos are from a marl bog at Macgregor Point Provincial Park, in Ontario, on the Bruce Peninsula, taken on June 22, 1982 and not of the marl bogs at Wilderness State Park, Michigan.  I say a marl bog is a marl bog and a marred blog is a marred blog.
