Found: stuff sack full of spices. If you lost one, let me know the details and I'll see if I can get it back to you.
This is a great network of trails for a 3-day, 2-night backpacking trip. We drove up on Friday night and car-camped at the trailhead. Reading the trail description, we expected a bunch of sites. There were only a couple, but luckily we were able to get one.
On Saturday, we hiked down to Mazama Camp, setup tents, and then hiked up to Park Butte. The views were impressive in all directions. We hung out up there for a while waiting for the clouds to leave Mt. Baker. They stuck around until about 30 minutes after we made it back down to Mazama Camp. At least we had a nice view for dinner. There is a small stream that makes a good water source.
There is a bathroom at Mazama Camp, but for some reason the sign had been removed. We had to do a bit of searching, but managed to find it. The trail to it starts next to the shelter. There was a bathroom sign and some freshly split chunks of logs next to the shelter, so I used those to mark the trail to the bathroom.
The next morning we headed up to Railroad Grade. This is an amazing trail, but might not be great for people afraid of heights. The entire way is along the top of a ridge, with a sheer drop-off on one side. There are a couple of places where the trail is a little eroded in that direction, but for the most part the footing is good.
On the way up Railroad Grade, we discovered a much nicer place to camp. My wife hung out to claim the site while my friend and I went back and packed up the tents. We got back shortly before the clouds cleared from Baker, and had an amazing view during dinner, into the evening, and the next morning. Strangely, this campsite was much warmer than the one down at Mazama Camp, despite being several hundred feet higher in elevation. There is a small pond that we used as a water source. We also pumped water from a small pond at the top of the Railroad Grade Trail near Sandy Camp, and found that to be much tastier. The one downside of the camps on Railroad Grade is that there is no easily accessible bathroom. The closest one is 15 minutes away, which seems like an oversight on the part of the land managers.
The next day we hiked out via the Scott Paul Trail. Again, I was impressed both by the beauty of the trail and by how different it was from the previous days' trails. The suspension bridge was especially fun, though people who are afraid of shaky bridges with open sides might disagree.
The trails were generally in great condition. However, there were a couple of blowdowns on the Scott Paul Trail, including one rather large one.
