As I am working on completing the 100 Peak Challenge for a second time, I needed to climb East Mesa – Peak 5178. When I did the challenge in 2019, I climbed East Mesa High Point, as Derek did not define which East Mesa to summit. He later clarified that the correct peak is East Mesa – Peak 5178. Rather than simply hiking out and bagging the peak, I opted to camp at Granite Springs Primitive Campground, which is just a short distance from the peak. I bought my overnight permit from the kiosk at the Green Valley Campground (Friday through Sunday, the kiosk is staffed), then drove the short distance to the Sweetwater parking area. I grabbed my pack and headed up the Harvey Moore Trail. The trail starts climbing right from the trailhead, so the light breeze that was blowing was welcomed. After about 0.7 miles, the grade lessened, and I kept cruising along. Oakzanita stood off to my right, and Cuyamaca and Cush-Pi (Stonewall) stood far off to my left.










As I passed through East Mesa, I spied East Mesa – Peak 5178, and considered climbing immediately after I set up camp, but I wanted to secure my camping spot first. Soon, the water pump came into view, and I had arrived at the campground. There were three sites here, so I went down the trail past the pit toilets to view my options for the evening. I settled on site #1, under the shade of some large oaks. The other two sites looked fine, but this one also had some nice logs to sit upon and relax. I set up my tent without issue. I had wanted to try a new pillow on this trip, and accidentally brought my old one instead (I actually brought both, but did not see the one I wanted to try until the next morning!). Since it was still Passover, I could not eat a dehydrated meal, so I had packed other food for my time out there. I also decided to bring my own water and not treat the water from the pump. The sun soon dipped behind Peak 5178, and it began to cool down. I slipped into my tent and relaxed, listening to an audiobook until I drifted off to sleep. I got up once during the evening and grabbed a few night shots before huddling back under my quilt.
















Around 6, I woke and had my breakfast. That hot coffee sure hit the spot. My thermometer said it dropped to 38°F overnight. I went back down the East Mesa Fire Road for a short distance before heading cross-country toward the southern slope of Peak 5178.
















Initially, the slope was covered in simple grasses and ankle-high brush, but as I worked my way up, the vegetation began to change. With about 40 feet of elevation to go to the summit, I now had to bushwhack my way through the last 100 yards or so. The brush was thick, and more than once, I would try one path, only to reach a thick wall. With a little luck (and a few drops of blood), I reached the summit. A small rock cairn denoted the peak. I could see the fog below me, which made for a unique view. Once I had taken in the view, I whacked my way through the brush and back onto the southern slope. As I cruised along the Harvey Moore Trail once again, I began descending into the fog. I stopped and slipped on my jacket before continuing. Soon, I was back in my car and ready to head home after a great overnight trip. The hike out was 3.9 miles with 979 feet of gain. The side trip up to Peak 5178 was about 300 feet of gain and took about 35 minutes. I think I will find the time to explore the other primitive campground, Arroyo Seco, before too long.
I am an avid peak bagger, sometimes backpacker, and former sea kayaker living in San Diego. In 2019, I became the third person to complete the San Diego 100 Peak Challenge. Not stopping with that accomplishment, I set my sights on the harder San Diego Sierra Club 100 Peak list, which I completed in 2021. In addition, I have conquered several Six-Pack of Peaks challenges (SoCal, San Diego, Central Coast, and Arizona-Winter). Beyond attempting the San Diego Sierra Club 100 Peak list a second time, I am looking forward to exploring new summits and new adventures across the southwest.
