Dear Mom, guess where I am writing this letter - I am sitting on the edge of the Grand Canyon! We leave Santa Fe two nights ago and arrive here early yesterday morning. And let me tell you, the Grand Canyon is really GRAND! I have already taken a lot of photos so that you can see them, and soon I will take a few more, but in fact, Mom, you won’t believe how great it is! It extends 277 miles from end to end — at a depth of a mile, and in some places — at a mile — and there are so many incredible colors in the rock! Blues, reds, violets, oranges, greens, yellows, and so on. There is a funny story about how the Spaniards first discovered the canyon. When the Spanish explorer first came here in 1540, he sent two of his men to the canyon for research. He told them: "Go there and quickly inspect." Quick look around! No wonder they will never return. They just die there, as long as they have a "look around." You see, the Spaniards never imagined even something so big, so they cannot guess its real size. In any case, we are probably going to spend several days here, but we have not yet decided what we will do after this. See you in a couple of weeks. Love, Mike.
