John Wesley Powell Descends the Colorado River

This year we visited the Grand Canyon of the Colorado River, a place which gets about 4.5 million visitors a year.  Most of these visitors never descend into the canyon and until a century and a half ago, most of the canyon had never been traveled by anyone.  Indians of the area descended into the canyon and even farmed and lived there in certain areas, but they were not able to and did not travel along the bottom of the canyon for any distance.  Travel at the time was in and out of the canyon but not along the canyon. 

John Wesley Powell changed all that.  The American Civil War had just ended and Powell who had  been a Major in the Union Army organized an expedition to explore the Colorado River and its tributaries.  The US was still relatively young.  Americans were still moving west and if the movement west was going to go forward in earnest then transportation routes were needed, not only to bring people into the region but also to export resources out of the region.  Major Powell was the man to find those transportation routes.
I knew the basics of Powells story but after my own trip to the Grand Canyon, I pulled Powells report of his journey off my book shelf where it had sat unread by me for a number of decades.  It was time to upgrade my knowledge of this piece of Western history.
I have not finished Powells book so this is an incomplete report, but this being a boat related blog, I will focus on Powells means of transportation, that is, wooden row boats.

Powells boats with one or two exceptions were 20 feet long, made of wood with extra frames added for strength. The front and back ends were decked over and closed off to form water-tight compartments in which food and gear were stowed.

The journey began on a tributary of the Colorado river in territory where the canyons were not yet as imposing as farther down the river.

The expeditions first camp is shown here.  Notably absent from the picture is any kind of plastic, a substance without which modern camping and river travel would be unimaginable.

As the journey progressed, the canyons became deeper and the expedition encountered falls and rapids.  The picture above shows one of the options for dealing with rapids, that is, to run them.

Other options for dealing with rapids were lining the boats down the rapids and portaging.  In either case, the usual method was to assemble the boats on shore at the head of the rapids and secure them while scouting the rapids.  Where possible, the boats were lined, that is, led down the rapids with lines tied to both ends of the boats. 
If the rapids were too severe the boats needed to be unloaded, the gear carried to the bottom of the rapids and then the boats.  All this took time and lots of work. 

Powell and his crew explored new territory and also inadvertently invented a new sport: river running.  This sounds like not that big a deal since totally inexperienced travelers now do this trip every year albeit with experienced guides.  But what made it different for Powell and his crew was that none of them knew whether their boats would survive the rapids or what the severity of the rapids would be.  They also lacked modern gear and were cut off from civilization for most of the trip.  Conditions were sufficiently horrid to make some of the men quit.

Trouble in river city

The photo above illustrates what happens when you build things in the dark and do not follow the instructions to the letter.  This is a 1/4" gap running from the plywood scarf (I did a pretty poor job on the scarf) to the stern.  The pencil line outlines the area that is the dip of 1/4"  it tapers down to normal pretty quickly outside of this area.  This is caused by the combination of the scarf being roughly done, and by the very last 2-3 inches of the stern bottom seam not being completely pulled in.  I think the dip got worse and the sides came in and I really did not see it until all had been wired up and taped and the boat flipped over outside a few weeks ago.  That said, I now need a plan to fix it.  I came up with three ideas.  

1.  ignore it and it will go away.  

2.  foam core and glass over

3.  wood core and glass over (similar to balsa core, but using 1/4" okoume.  

I went with option 3 and things are gradually improving, but it still takes a ton of filler (WEST with microballoons and a little thixotropic powder thrown in.)  

Along the keel area I have laid out a thick paste of microballoon and then cut up squares of Okoume to fill the deepest voids, just going as far as the 1/8" dip.  

another view. 

Since then, I have started to fill with the microballoon paste, and will sand with the long board to get all fair prior to glassing.  I am pretty sure that when all is said and done, no one will know it is there.  Microballoons are a boatbuilders best friend.  

I hope to get a better photo posted next weekend showing how this all blends in nicely.  If it doesnt blend in,  I will make good use of the wood eraser.

Much better now.  The stern is starting to get flat, and dip is disappearing.  It takes lots of filler. But, It looks as if the plywood is at the right height, just slightly above the dip and is easy to fair with the long board. 

I will bring the filler out to the edges after hitting it with the long board to find the high and low spots.

At this point, I am wishing I had applied foam core and shaped it.  This is taking more filler than I imagined it would.

after a rough sanding with the long board, I went at this again with a thinner coat of filler.  It will take at least one more sanding and filling to get it to its final shape.  It is actually coming out well.
