Of my two trips to Yellowstone, this one stands out for the thermal features and the Grand Canyon of the Yellowstone. The weather cooperated beautifully as we toured both the geyser basins and the Canyon area. Brilliant sunlight really brought out the colors in the hot springs and the clear blue skies made a perfect backdrop for the erupting geysers. I also had the incredible luck to see an eruption of Giant Geyser. It only erupts six or so times a year and when it does it sends a column of water and steam 200 feet into the air.
On the other hand, while we had some good wildlife encounters, they did not compare overall to the ones we had in 2007.
