Borup Loop

Click for larger image

The Borup Loop carries trains between Borup and the Stampede Pass Tunnel en route through the Cascade Mountains. Between Borup at 2,270ft (691 m) and the west entrance of the Stampede Pass Tuneel at 2,900 ft (883 m), the elevation difference is 630 ft (192m) over a distance of 2.3 miles (3.7 km). Clearly visible in the satellite imagery as it crisscrosses Sunday Creek, the Borup Loop is not actually a loop at all, but an elongated ‘S’ curve formed from back-to-back horseshoes.

The Northern Pacific Railway completed the Stampede Pass Tunnel in 1888 as a direct means of reaching the Puget Sound from Yakima, WA, rather than the roundabout way along the Columbia River. The line operated for a century before being shutdown in 1984 by then-owner Burlington Northern. A little over a decade later, the line was resurrected to handle increased freight traffic into the Pacific Northwest.

We first learned of the Borup Loop at our campsite below Snowshoe Butte, where we watched from the south as several trains passed through. We got another view to the loop, this time from the north, while camped along Forest Road 5000625. This was another great campsite, with wonderful views across fields of wildflowers to the Snow Creek Valley. While there, we also tested out our new privacy tent and camp shower for an upcoming 3-night camping trip.

We didn’t get very far exploring down National Forest Development Road 620 before it became too overgrown. We could have pushed through, but it’s really tough on the car paint and we weren’t confident enough that any good campsites were beyond.

Retracing our path along NF-50, from NF-620, we found a lovely spot off the edge of NF-5000625 with wildflowers all around. The road dead-ends not far beyond our camp, and we only saw one other vehicle the entire time we were there.

We were super-excited to hear a train, and see one passing through the Borup Loop that we’d seen earlier from our campsite at Snowshoe Butte on the other side of the valley.

Snowshoe Butte
From our campsite along NF-5000625, we could see a truck with a roof tent at the Snowshoe Butte campsite we were at three weeks ago.

Privacy Tent
We’re planning to take a 4-day camping trip at the end of the month and want to be able to shower. The first part of making that work is a Your Choice Privacy Tent.

Camp Shower
To have a shower at camp, we bought a Kradl Portable Camping Shower. The shower holds 2.9 gallons of water and builds pressure through a foot pump. Here James is testing out the flow, which seems pretty decent.

Camp Toilet
The shower enclosure also works well for our camp toilet.

Our little SUV doesn’t have the ground clearance of a real 4×4. It can actually get up pretty steep hills, but where it quickly runs into problems is with ground clearance, especially forward.

The reward for taking on that steep hill is a beautiful private campsite overlooking a small lake.

Mt. Rainier
Mt. Rainier burst into view as we explored along NF-5078. Big ruts in the road prevented us from proceeding much further.

As we explored today, we encountered several groups of people parked off the side of the road and off doing something in the woods. They didn’t appear to be camping or picnicing, and likely were harvesting berries or some other plant.

Crossing the Pacific Crest Trail on a spur off NF-5483. We walked a short distance on the trail when we were camped at Snowshoe Butte.

The Commonwealth
The view from The Commonwealth at Snoqualmie Pass where we stopped for lunch on our way home from camping. The pickup backing out doesn’t look unusually large in the picture, but looked towering when it was closer in the parking spot.

Boeing 777 Flyover
We caught another instance of the Boeing 777 Flyover for the Boeing Classic PGA golf tournament taking place at the Club at Snoqualmie Ridge. We’d seen this a couple of days ago, from above, at Mt. Si.
