Using the marker on the map in the app, I was brought to a small dirt parking lot off the main road. Further exploration showed that a dirt road continued into the vegetation. I followed it, but it turned and went parallel with a road. I am nowhere near see the marker on the map. However, I am a 100 feet off the trail overlooking the town of Borrego Springs and the mountains behind it. I am here in this section by myself.

I did explore the Yaqui Pass and the Yaqui Wash spots, which are both further west over the mountain. The Pass was great and within a valley. The pass was a carpark as someone else noted. I wanted my back to the sunset (and the wind) so chose this location. Next time I hope to get to the spot the other reviews seem to be at.
