Flat Mountain Pond Backpack

My friend Kris and I did a one-night backpacking trip to Flat Mountain Pond, in the Sandwich Range on the south side of the White Mountains. Located between Sandwich Dome and the Sleepers (mountains named after Kate Sleeper), we camped at the site of the Flat Mountain Pond shelter which is an easy 5 mile walk from the Flat Mountain Trail trail head parking lot to the pond along an old railroad grade.

Only we didn’t take the trail to Flat Mountain Pond, we bushwhacked to it, bagging South Flat Mountain (2940′) en route, a New Hampshire 200 highest peak. This was the first bushwhack that Kris and I have done together this year and the level  of effort walking steeply up a mountain off-trail caught me by surprise.

Scrambling over blow downs and ledges is many times more strenuous than hiking on a well-graded and intentional trail, even the rocky trails we have in the Whites. Still the woods on South Flat Mountain were quite open, probably because this area of the White Mountains was clear-cut and so heavily logged by the timber industry before the logging railroads were shut down and the land declared a Wilderness Area.

I was feeling like my old self by the time we reached the summit however, although the bugs were simply ferocious and swarmed around Kris and I as we checked out the views of nearby Sandwich Dome from the top of the mountain. Seeking a respite, we quickly hiked down the north side toward Flat Mountain Pond and the shelter there, passing through open fields of birch and old timber slash, now boggy and overgrown with ferns.

After wading though a short section of stubby spruce, we were surprised to come across this stream, which was not an off-trail landmark we’d anticipated. While the stream is present on older historic maps of this region, it’s not on the Caltopo USGS maps we’d printed out for our hike. The stream was very easy to cross however, and it was a short hike to the Flat Mountain Pond campsite and shelter after that.

While we planned to spend the night camping at the shelter, it was still before noon. In addition to bushwhacking the southern peak, we’d also planned to bushwhack Flat Mountain, also called North Flat Mountain (3331′), a short distance away.

Though 400′ higher than the southern peak, climbing the northern peak was only about 1000′ of elevation gain instead of the 2000′ that we’d climbed that morning. While still moderate, this second bushwhack was harder than the first because we had to detour around more ledge and pass through a section of high elevation bog to get to the summit. My socks and shoes never smelled the same after that muddy encounter.

Kris and I were already tired before for this second climb because were carrying full backpacking packs in anticipation of camping out that evening. Bushwhacking with a backpacking load, even though it’s relatively lightweight, proved to be strenuous for us both.

The bugs were also far worse on this peak than our first bushwhack and we were quickly covered with mosquitoes, black flies, and regular flies whenever we stopped for a drink or to consult our maps. I even put DEET on my hands, neck, and ears, which I almost never do, despite the fact that were both covered head to toe in Insect Shield treated clothing.

We were dragging a bit when we reached the summit, but we quickly found the summit canister as well as an old-style logbook. I love these old register covers because they hearken back to an era when the Appalachian Mountain Club was less corporate and more focused on trail building. hiking and mountaineering than it is today. We were the first party to have climbed the mountain since the previous June, nearly a full year earlier.

While the number of entries in the log book was small, I recognized many names of friends that I’ve bushwhacked other trailless peaks with, or people who’s names I always see, but have never met. One name in particular stands out, a guy named Zach Porter, who’s the Cold River Camp Cook. I expect to meet him in a few weeks finally, because I’ll be working at Cold River Camp (in Evans Notch) guiding hikes for the AMC as a resident leader.

Overcome by insects one again, we hightailed it down the northern peak and back to the pond to camp for the night. The pond itself is breathtakingly beautiful and we had gorgeous weather that evening and into the night, with bright moonlight that back lit scattered clouds overhead. I can’t believe how lucky I am to be able to visit these remote spots on a weekly basis in the White Mountains. The summer is still young, but I already feel like I’ve visited many special places.

Kris and I are both early risers and while we had a casual start the next morning, we broke camp and started hiking out before 8 am. This time, we stuck the trails though, hiking out on the Flat Mountain Pond Trail back to our cars 5 miles away. Following an old railroad grade, complete with occasional railroads ties and iron rails, we made extremely good time, taking just two hours to hike the distance.

If you’re looking for a really nice one night backpacking trip, I recommend that you check out Flat Mountain Pond. We did not see anymore for nearly a day and a half, it’s that remote.

  1. Lovely and reflective report, Philip. I like the way you counted your blessings in being able (both physically and in terms of life-style) to make these hikes into beauty and solitude. John Muir would find in you a companion voice.

  2. Excellent. Bushwhacks are the best!

  3. Sounds interesting. The name, “Flat Mountain”, is somewhat comical.

  4. Should have brought your Tenkara rod. I had fun with the native brookies there about 5 years ago. My friend and I had the place to ourselves and I fly fished from the spot you took your sunset picture. The fish weren’t out far either.
    We woke the next day to hear a bull moose grunting and calling for cows as the rut was starting. He obviously crossed over next to the wooden damn. As we got up to look out, he ghosted by walking toward the tent sites. Steam coming out his nostrils with a nice morning fog laying around his legs. A terrific picture moment……If my batteries hadn’t died because of the cold the previous night!

    • I left my rod in the car, but walked back in after we’d finished our trip and fished for a few hours on the bottom section of Pond Brook. A beautiful stream. I plan to go back soon and fish some of the pools upstream below that big horshoe curve in the trail.

  5. Nice trip. I really like one nighters, they bring so much fun in to your live and leave you with enough energy after that. Nice trip and nice post as usual.

  6. How were the bugs near the shelter at the pond. I’m considering an overnight there one weekend this month, but am hesitating due to the low lying area. Did they bother you too bad down by the pond.

    Love the post!

  7. Any idea if there is parking off Whiteface intervals Rd during winter? Seems like a nice spot for a quick winter overnight.

    • Upon further investigation and reading your other blog on the area it seems maybe Bennett St. would prove to be a better option. Any insight would be greatly appreciated.

      • I meant to post this earlier… There is indeed a plowed area to park to access Bennett St trail. It adds about a half mile to get to the official trailhead/kiosk. My brother and I made the trek out in January. We were able to hike rather quickly wearing our snowshoes as there was a hard crust on top of about 8 inches of snow. Firewood was hard to come by as the area around the shelter has been picked over extensively.

  8. This is the first I heard of peak registers / canisters, how do you find out what peaks (particularly in the Whites) have them?

  9. When I was a kid in the 70’s my dad used to take us in there to camp every summer, we would stay a week, but back then you could drive in, he had a 1965 Land Rover and 5 kids, and my uncle and a friend would take there Toyota landcrusier and a pick up and follow us, it would take 5-6 hrs to drive it, there was a bridge to cross the brook that only had a few boards on it, scary, as we got older the boards rotted away and we went to the left and crosse the water then back on the trail, my mom has a lot of 8mm movies of him driving in and us camping, there was an out house in back of the shelter, we girls hated using it, lol, seeing the pictures brought back so many memories, driving over those tracks was rough, sometimes us kids would get out and walk , my baby sister was 2 months old for her first time in, and we girls took turns holding her on the seat . Thanks for the memories
