Sulphur Works

Lassen Volcanic National Park

We stopped at the Sulphur Works where the highway crosses a hydrothermal area and we could have a quick look at steam vents and boiling mud. It stinks a bit and the rocks seem to have taken on a bright yellow in many places around it.

Just off to the side of the road, a mudpot bubbles and boils quite noisily. Click here to hear it.

Jennie Lakes: Belle Canyon and Rowell Meadow

Kings Canyon National Park Sequoia National Forest Giant Sequoia National Monument Click for map. DAY 1  |  DAY 2  |  DAY 3  |  DAY 4 It was another mild night, but the mosquitoes very nearly vanished early on into it. The sun comes quickly here and the morning golden hour is really quite something. I enjoy it with breakfast and happily the mosquitoes seem to be slow to wake up. Our northerly view from near camp: the morning sun as it hits Ball Dome. Morning over Ranger Lake. We head out to the trail again and wander gently downward, still high above the valley bottom. The air seems a lot clearer today and the snow on the far mountains is much more defined. The snowy distances.

Lost Coast: Cooskie Creek Route

Image
King Range National Conservation Area, Arcata BLM (purple line, map link ) DAY 1  |  DAY 2  |  DAY 3  |  DAY 4  |  DAY 5  |  DAY 6  |  DAY 7 I looked around at how soaked everything was from the dew and decided I had enough water to cook breakfast right there (well, on a rock under the Douglas fir) while waiting for everything to dry out a little. My windbreak trees became morning shade trees, but they were still blocking some strong gusts most excellently, so I wouldn't want to trade them. Good soggy morning! So I headed out on the faint old road to join a much better road until getting pointed off to the left at a gate. Trail gets really faint there, but it's all much easier to follow on the second pass than it was on the first. A bit sunnier, but most spots aren't much drier than they were. After the short road section, follow near the fence on the faint track. If truly desperate for water and it has rained well recently, there might be a tiny

Mount Lassic

Image
Six Rivers National Forest ( map link ) Mount Lassic actually has a trail up it, I just didn't know where. It was built (possibly by California Department of Fish and Wildlife, but still official and maintained) but not drawn on a map nor described except that its purpose is to move feet away from the rare lupine that grows over less than 4 acres in the whole world. All but a garden sized plot is on this mountain. I wanted to visit it, but not to stomp across its whole territory. (Also, I made really certain that my shoes were completely purged of any seed before arriving in the area. After Clover Gulch, that was a challenge, but worthy.) I decided to start off on a small trail I found by my parking. It was minimally flagged and marked and probably not the one meant for the public. There's a faint trail just to the left of the smaller tree here where the road drains its water. Weather seemed to be forming over the Lassics, as it had the last few days, but then roam

If the Map's Wrong, Fix It!

Image
OpenTopoMap (an OpenStreetMap service) showing my GPS track from backpacking in the Flat Tops Wilderness in 2016 . It is zoomed into the busiest entry point where one very excellent and well used trail is missing. The map in question is, of course, OpenStreetMap . While not explicitly setting out to do this, they've created the Wikipedia of maps and you probably use it even if you don't know it. It's on AllTrails and Strava and behind Gaia Topo and MapBuilder on Caltopo. If any of those have an error, you can fix it. There in the lower right hand corner on AllTrails is the attribution and an invitation to change and add to the map. It's not just on the internet. This is also the one electronic map I carry with me, offline , that I know it will cover the place I am. When I need a library, post office, grocery store, gas station, I can search and find it even if I haven't got any usable cell signal. The roads are (generally) there. The buildin
