Yosemite National Park occupies 1,190 sq miles of some of the most beautiful landscape in the world, but the the one mile wide by seven mile long valley floor makes up the most popular part of the park. This small section of real estate is where the vast majority of people spend most of their time. During the busy summer months the valley looks more like a crowded metropolitan city park than a dedicated wilderness area.

But why the crowds congregate to this small little plot of land is by no means an accident. They are there because Yosemite Valley provides some of the best scenery to be found anywhere in the world. John Muir called it the "Crown Jewel of the Sierra Nevada"  


Weather in Yosemite can range from 100 degrees in the valley during the summer to below zero in the upper elevations of the park during the winter. Yosemite Valley that rests at an elevation of about 4,000 feet has fairly mild temperatures throughout the year, but as you go higher, the temperature (in general) decreases 1 degree Fahrenheit for every 300 feet of elevation gain. Precipitation also increases 2 to 4 inches for each 300 feet of elevation gain reaching a maximum at about 5000 to 6000 feet. You will hit these elevations along the Mist Trail between Vernal Falls and Nevada Falls. Ninety five percent of the precipitation (both in rain and snow form) falls between October and May, with more than half (typically) falling in January, February, and March.

Psalm 103:11-13
For as high as the heavens are above the earth, so great is his love for those who fear him; as far as the east is from the west, so far has he removed our transgressions from us. As a father has compassion on his children, so the LORD has compassion on those who fear him;  for he knows how we are formed, he remembers that we are dust. As for man, his days are like grass, he flourishes like a flower of the field; the wind blows over it and it is gone, and its place remembers it no more.
