Not sure what this plane is but it looked interesting and was parked near the road in the proving grounds.

Following the road once you are inside the NWR takes you to a number of points that give you views of the Colorado River. We were told that the water level is down this winter as a number of sand bars are visible. Another stop along the road is the Painted Desert Trail.

I couldn't convince Ed to carry one of the big colorful rocks to truck.... I thought it would look great in my garden at home.

Taking a rest break. Even though the air is cool, the sun is quite warm.

Wildlife, such as black-tailed jackrabbits and western whiptail lizards are plentiful. Desert bighorn sheep, mule deer, coyotes and burros also live out here. In dry weather these larger animals head to the river for water.

The trail gets it's name from the colored rock you see as you hike in the area. The colors were created by 20-30 million year-old volcanic activity.

Ed has been fascinated by aerostat balloons flying in sky around Yuma. Though this aerostat balloon was far in the distance, being on the ground it was much easier to see than the ones in the sky. The helium-filled aerostat balloons hover at 15,000 feet and are focused on one thing: low-flying airplanes. Six-aerostat balloons form a radar fence along the southern United States watching for drugs being flown across the international border.
