I am not going to give a lot of statistics on elevation in this post. What is significant about elevation, as you would expect, is that this is a very deep canyon. Viewed from the rim, the Colorado River at the bottom looks like a tiny ribbon when, in fact, it is quite wide in all the places that you can see it.
Standing at various lookouts on the rim during my first brief trip, I remember feeling that rush looking out over the cliffs. You almost can’t help but think of what it would be like to fall, or jump. The drops are so extreme. ( I was saddened to hear the news last week of a tourist who fell to his death. Taking pictures can be hazardous. )
The rims vary from 6000 to 8500 feet above sea level. The drop down to the river at the bottom of the canyon varies from 3500 to 6000 feet. Our gain/loss of elevation on Day 2 and Day 4 of the hike will be about 5,000 feet. That is enough difference in elevation to produce a climate change. It is often much cooler up on the rim and quite warm to very hot at the bottom.
That might make it tricky to pack the right clothing. In May, when I am going, it should not be oppressively hot at the bottom and hopefully, it won’t be snowing up on the rim.
This is what I can expect for May weather:
South Rim (where we start) Max 70 degrees, Min 39 degrees, Precip 0.66 inches
Inner Gorge (lowest point) Max 92 degrees, Min 63 degrees, Precip 0.36 inches
One very curious fact – the plateaus on both sides of the canyon are higher than the elevation upriver. Why did the path of the river run from low to high elevation when it first began cutting the Grand Canyon? Of course, it didn’t. There are several theories about why it appears this way. None of them are certain. Geology is sometimes very strange and although it has stories to tell, we don’t understand them all.
I will end with a picture of one of the bridges that we will cross at the bottom of the canyon – a bridge that still seems scary high, even though it is dwarfed by the walls of the canyon.
