Water’s up, but for how long? These creeks are flashy by nature and will rise and fall with the rain. The million dollar question right now is what these streams will look like in September. Here is what the Mad at Arcata looks like right now:
You might notice the variation in flow – notably the 3000 cfs increase in the past 12 hours. Impressive. And that is nothing compared to what the Eel is doing: Its off the charts! Yes that is a 45,000 cfs increase in flow over a 12 hour period. Fortunately it does not tend to drop off as fast, however you can see how over the month, especially for the Mad River, the rivers are still way below where they normally are for this time of year.
Here are some pictures from way up near the headwaters of Grizzly Creek. The forest is right on the redwood transition areas where redwood and coastal Douglas-fir and oak woodlands collide. The combination of good soils, heavy rain, and persistent fog make these areas very productive for trees.
These mountain streams may look small, but once the rains start they really pick up. Most of the headwater areas transition to open grasslands, and as result the peak flows into these streams is enormous. Flows tend to be flashy and can be very intense right after big rains.
This particular forest came with an interesting story. Most of the surrounding areas where logged in the 1960s. Apparently as they moved into this stand, there was a horrible accident, costing one of the loggers their life. The crew backed out after the accident, leaving this area unlogged. And so it has stood until now. And so it will remain, now that a northern spotted owl has found its home here.
As you travel east and into higher elevations, the forests begin to transition to a mixed conifer type, which is generally defined as Douglas-fir and/or true fir with pine and various hardwoods. Mixed conifer forests are pretty complex and can vary widely across the interior of the state, but thats another story.
Only the eastern and more remote portions of Humboldt county have these types of forests, though occasionally you may find islands of habitats that resemble mixed conifer and form unique areas on the landscape. (e.g. willow creek, south fork mountain, etc.) This place is near the pilot drainage and is nestled within a thousand acre oak woodland, where just about 10 acres have developed into this unique forest island.
Here is another example of what I would say was natural encroachment of oak woodlands, or better put, succession. There are a few aged white oak trees, but they are in severe decline. Most of the woody debris on the ground and standing snags are white oak, a last testament of what was there a few hundred years ago. This forest obviously developed with fire as all the trees have layers of fire scars, including this madrone.
Here is a good view of a stand that has almost fully transitioned from a black oak forest to a Douglas-fir stand. Encroachment began in this stand in the 1960s and finally the last of the taller oaks are reaching the end of their lives. Over then next ten or so years the oak stems will loose all of their limbs and begin to feel the pull of gravity as their root masses die. Many species of insects and fungus will invade these trees and speed up the fall. Once on the ground, the boles will persist for decades as the forest recyclers slowly and consistently do their work.
Meanwhile the Douglas-fir canopy will close in around the space previously occupied by the oaks and the little remaining areas of filtered light on the forest floor will become dark. This will also effect the shrub and ground cover component of the forest, severely limiting what can grow there in the absence of light.
Its interesting how the full encroachment cycle changes the bio-diversity of stand over time. It would seem that during the last phases of transition, like in the photo, the diversity is highest. This is in part due to the vertical structure offered by the overstory conifer, the decaying oak trees in the mid canopy, and the collection of downed wood on the forest floor. There are also pockets of shrubs that still receive light where the fir canopy has not closed in. Oak snags make potential cavities for numerous birds and mammals. The fallen trees become home to hosts of insects that in turn are feasted on by many of the locals.
While I generally speak of this encroachment as a negative, there is certainly a positive, or at least productive element to this process from a forest health prospective. In a truly “natural” setting, there would be recruitment of oak woodlands somewhere near-by while this process was occurring, creating the balance of habitats over the landscape. However in our fire starved environment, Douglas-fir encroachment is occurring much more frequently than the rate oak stands are developing. In fact, very little oak stands are developing at all in Humboldt County. This is why, I believe, that there is an urgency to prevent encroachment into woodlands.
Leave it to children to be able to find neat places that you would otherwise never see. How often are you at a place like Moosntone Beach and have the desire to go crawl through the brush just to see whats in there? I used to have that urge, and while I do crawl through the brush at work, its the last thing I want to do when Im not working. But its hard to turn down your kid, so adventure it is. Lead on boy!
He had been going on and on about this so-called “sand slide”. Essentially Moonstone Rock is a sandstone bluff, almost completely covered with a mat of English ivy. Animal paths have been expanded by kids and make a maze of tunnels to explore. Once I got in there I remembered exploring these ivy tunnels as a teenager.
Although this is an exotic, invasive species – it sure is pretty looking. Who doesnt like to look at a ivy covered castle or brick wall? And ivy caves make for wonderful adventures. Once they really dominate an area like this, there is certainly habitat for many birds and mammals.
I have wanted to hike around this forest for years. You can see this area from the highway and can access it pretty easily from the East Fork Camp ground when its open. I happened to have some extra time last month and hiked up into the forest a little west of the camp ground from the 299.
This forest has it all. Douglas-fir, tanoak, madrone, golden chinquapin, and more. The understory has the same species where light allows, as well as the occasional pacific yew. Sword fern and huckleberry make up the bulk of the ground cover. Eventually I saw a huge tree that appeared to be the biggest in the area.
I only has a few hours, and Id like to get in here someday and explore a little more thoroughly. The campground looks like a nice escape from a hot summer and even in this dry summer we are gearing up for, I bet the East Fork will keep water.
We had a nice dusting of snow last month and since then barely a drop of precipitation. As drought concerns heighten, time to start thinking of conservation of water. Or participating in a rain dance. Or both…
I have promised myself for years to check out a few of the peaks that are right on Route 1 when I had the time. I finally did last December and stopped to check out Blake Mountain.
Next I went over to Blake Spring Campground or at least what is left of it. An old jeep road runs down to the spring, but there is not much of a camp there. There is little flat ground, and it appears that camping on the ridge would be more comfortable. Perhaps the road used to go further past the spring to a more suitable spot, but if there is a road it is completely over grown past the spring.
Just to the north of the camp is the high spot on Blake Mountain. A jeep trail traverses the ridge and the bench mark was easy to find.
From there you can check out the “South Fork” bench mark, a little further to the north. I would like to know how this spot got its name, as the ‘real’ South Fork Mountain peak is many miles to the south. Regardless, this is a neat spot, and perhaps the most interesting of the three bench marks on Blake.
So 2013 has come and gone. Happy New Year! I put up my 2013 gallery page and had a real hard time finding my favorite picture of the year. Looking back, I think my hike up to Blue Rock was the coolest thing I did, with the Mad River steelhead dive coming in close second. Here is the view from Blue Rock:
Be sure to look though the 2013 page now added to the top of the blog.
When I returned from my recent trip to southern California, I had the pleasure of being held on the plane circling for an hour before being sent back to Sacramento. As beautiful as it was in 90% of the county, apparently there was heavy fog at the Aracta airport – and well, you all know the drill around here. At least I got some awesome views of our county. This is over the central-east portion of Humboldt. If you note the savannah-grasslands above the wing, you can see Indian Creek, which is in between the two open ridges. From this vantage you can really see how isolated the oak and savannah types are becoming, as they continue to be rapidly encroached by Douglas-fir.
When I took this picture, the plane was right over McClellan Mountain. The Van Duzen River cuts through the melange geology here. You can still see the grey scars remnant from the 1964 flood. The strange formation in the center of the picture is the Eaton Roughs. I have written about the roughs previously here: http://nooksand.wordpress.com/2012/11/30/the-desolation-2/
In a recent trip, I visited the southern California town of my youth, La Crescenta. Although it was a short trip, I had to take a quick morning hike up into Pickens Canyon, where I spent many teenage days and nights exploring some of LA’s hidden open spaces.
This creek at one time was the principle water supply for the rural community below, which eventually became La Crescenta and Montrose. If you look carefully in the pictures you might see the old water pipes that were installed near the turn of the century. We used to use them as supports, climbing along them to get higher up into the canyon.
A wonderful coast live oak here in all its fire adapted glory. There was a fire in this canyon in 2009 which has substantially altered the vegetation from when I was last there – over 15 years ago. And while I did note some tree mortality, most of the mature trees, particularly the ones hanging on the canyon walls have survived. I also saw the canyon live oak and the California scrub oak, as well as maple, alder, and willow species.
Another observation was of the apparent debris torrent that has scoured the stream channel in places and deposited sediments in low gradient areas. These mountain streams are very incised and have many narrow, steep side channels making their watershed areas larger than you would think – the result is a huge peak flow result, especially after fires have burned most of the understory vegetation in the upper portions of the watershed. Here is a video I found of the recent floods, taken about 1 mile down from where my pictures were taken:
Wow, and that was nothing compared to what happened in the infamous flood of 1934: http://www.cvhistory.org/thennow/pics/pickensfloodcontrolthen.jpg.
A view out of the canyon. Bye-bye LA. Hopefully next time I will get to spend some time in up in the Angles Crest.
So we have seen these historic sites and objects, some close to 100 years old. However people have existed in the same areas for much longer. These sites, while a little harder to find, have persisted for centuries – some for thousands of years. I think the oldest recorded site in California is over 10,000 years old! In the picture above we found two archaeological sites in this valley and believe that it is likely that there are probably more sites deeper down in the ground. Hundreds of years of erosion and soil development essentially cap sites. Here are two of the artifacts that were discovered close to the surface.
