The winter elements adds an extra dimension to the images. We are very familiar with seeing summer images of the Grand Canyon, but the snow and different lighting conditions adds some special effects.
I have been to the Grand Canyon many times. I have visited both the North and South Rims in good weather, and when the North Rim closes after a good snow fall, we only have the South Rim to visit.
The South Rim road conditions can be hazardous, I have been there when they were solid ice. Also, my GPS would not recognize the town of Tusayan (where many hotels are located), located on Route 64/US 180 south. I entered the park on Route 64 heading west from the intersection with US 89. At some point, my GPS kept telling me to turn around on Route 64, and I saw three other cars pull over (it was night, dark & cold). I assumed they were told by their GPS to turn around too and did. What stuck in my mind, was a memory of seeing Route 64 running south from the parks visitor center in my road atlas. I always carry maps with me to bail out the GPS when necessary.
