.So,
we made very good time even though the wind was blowing upstream the
first day. We camped in the same spot as we had on the previous
trip. We could tell that it had had a lot of visitors since we had
last been there. Some of the vegetation was trampled and new
trails up from the beach had emerged. Anyone who thinks that
rafting, hiking, biking, etc. doesn't have an impact on the river
corridor is fooling themselves. We do impact these places.
We need to be as careful as we can be so that the next boating party
down the river has the illusion that they are discovering the river for
the first time.
Well,
where we stayed the first night became our day long resting place as it
rained the whole next day. We were making such good time though
that we could spend a whole day staying out of the rain. Tom and I
read most of the day and tried to stay warm. It's easier to stay
warm when you move around. In the picture to the right, you can
see Tom making pancakes. This is a new luxury item for this year's
rafting season. Usually, we only eat oatmeal.
On
the third day, the sun came out and we were on the river again. We
headed down toward Mexican Hat and the Raplee Anticline. A
beautiful thing about the west is that the erosional and geological
processes are not obscured by vegetation. The Raplee Anticline is
really a big bulge in the earth. What you see in the picture below
is the erosion of one side of the bulge. It's really very
spectacular and gives you a real sense of the earth bending. You
know that the bend means some of those layers you see off in the
distance are below you right now, which means that all the earth in
between you and those layers has already eroded off the anticline in
front of you.
You
begin to get a sense that yes, hundreds and even thousands of feet of
rock were once here piled almost a mile deep and that it has all eroded
away for miles and miles around you. You begin to sense that
humans haven't been around very long in the timeline of the earth.
Even if you could erode away a whole inch of ground each year, it would
take 630,000 years to erode a mile. And what about the time it
took to lay down the sediment in the first place? You being to
understand the vast scales of time, but it still boggles your mind.
In
the picture to the right, Tom is rowing down river with the Raplee
Anticline in the background. Notice the ever ready groover (the
white box) in the foreground. That's the bathroom! Cool,
huh?
A little further on, you come
to the goosenecks of the San Juan River. Basically, the story is
that the San Juan river used to roll back and forth across a shallow
plain, much like the Mississippi River does today. As the earth
lifted due to tectonic forces, the river kept its same course, but it
dug in a bit, then a bit more and finally you have firmly entrenched
meanders.
