The roads in Kofa National Wildlife Refuge are not friendly to large or fragile vehicles. Most ARE navigable, at least to a degree, with a sedan, but large cobbles, recalcitrant protuberances along with creosote and cacti eager to "reach out and touch someone" can intimidate those who have concerns.
There's a campsite a few hundred feet before this short section. Getting down wasn't too hard and though I suspect it wasn't necessary, I used four-wheel-drive low to get back up.
Phoebe is my first four-wheel-drive vehicle and I'm still in discovery as to her abilities. The difference between the apparent ease with which she navigates terrain compared to the experience behind the wheel, is still a surprise.
