Landsat image. At 277 miles long, 5 to 18 miles
wide (average 10 miles wide), and about 5700 feet
deep (just over a mile), Grand Canyon is not the
longest, deepest, widest or steepest on Earth,
but it may be the grandest for combining length,
depth, width and steepness. South Rim Village (S)
and North Rim Village (N) are indicated.

Historical Photo, helicopter-rescue training
exercise. National Park Service web site
says Over 250 people are rescued from the
Canyon each year. The difference between a great
adventure in Grand Canyon and a trip to the
hospital (or worse) is up to YOU - follow the
rules of smart hiking and - DO NOT attempt to
hike from the rim to the river and back in one
day, especially during the months of May to
September.

California condors have been reintroduced to the

It is a pleasure to see them wheeling above the
vast spaces.

Metamorphosed rocks abraded and polished by

river-worn rocks look very different from
glacier-worn rocks, but show clear evidence of
erosion.
