Today, the second day of an “atmospheric river” storm, I hiked the Montini and Overlook properties to check out how well the water was getting off the trails. More water was running off than I recall ever seeing before, although I had missed the October storm which by all accounts was a gangbuster.
You know it’s a major storm when the waterfall on the Holstein Hill trail on the Montini Preserve is running as it was today (see photo).
Most of the trail structures put in place to get water off the trail were working as intended, although a few need to be cleaned out or enhanced. The properties are so rocky, however, that in places water seeps from the hill above and sheets over the trail. In other words, there’s just no getting around having water on the trail, so be careful.
Today I realized that the invasive species removal season had started — earlier than it ever has during my tenure. The earliest I had started removing Italian thistle from the Sonoma Overlook and Montini Preserve properties had been in December. But now, with our early rains this season, the thistle has already started coming in (see pic). This essentially cuts my “down time” from four months to three, meaning the thistle removal season is going to be nine months long this year. Ouch!
One nice thing, though, is that I will have a three-week “vacation” in May, when I put in on the Colorado River rowing an 18-foot raft for 17 days. Since I just recently got off a 19-day trip doing the same thing, call me one lucky guy!
But mostly I’ll be out there, day in and day out, pulling these plants so that we can eventually eradicate them, as we almost have with the Yellow starthistle.
Walk Sonoma History through Sonoma Mountain Cemetery
Saturday, October 30
Times: 10:00 OR 12:30
Suggested Donation: $35.00
THIS EVENT IS NOW SOLD OUT!
Please join us next year….
The Sonoma Overlook Trail Stewards are thrilled to invite you once again to a lively, informative tour through our historic cemetery with our own amateur historian Fred Allebach!
Each year (except 2020) Fred has led this walking tour where we meet cowboys and Indians, ranchers and real estate tycoons, farmers and farriers, carpenters and stone masons, quarry-men, grocers, butchers, bakers, maybe a candlestick maker, and many more!
Fred will host 2 walking tours, one at 10:00am and another at 12:30. Both will be limited to 25 guests. We will be observing current Covid-19 protocols so please bring your mask.
You guessed it, yet another invasive species post. You can check out right now if this doesn’t appeal. I would be the last person to fault you for it. For those of us who do it, we recognize it as the obsession that it is. We don’t expect anyone else to be so afflicted Like, EVER.
If you’re still here, this is what’s happening. I’m laser-focused on pulling all of the Yellow Starthistle I can possibly find, as it is blooming now, and racing into seed. And yet we have a window of opportunity to make a serious dent in it this season. We are down to just some areas along Norrbom Road, and after hitting it hard last year, the impact is very evident. I’m finding much less than last year in these areas.
This affords us the opportunity, for the first time ever, of potentially pulling every single plant we see.
That’s why I’m fired up, and going out there every day I can, and pulling every single plant that I can, no matter how small. Because that’s how you reach your goal. Because that’s what it takes to completely eradicate an invasive species from 200 acres of public lands.
If you can’t do what’s required to come in hot, then you have no business taking this on in the first place. Just trust me on that.
Today Jessica M. and I (both volunteer stewards) tackled a Montini trail project that I had long planned. There was a place on the Rattlesnake Cutoff Trail where water, during heavy storms, would flow across the trail. Since the initial construction of the trail didn’t take this into account, the water would pool on the trail, leading to a long trail segment that would essentially turn into a tiny lake (see photo).
The Montini Preserve was heavily mined in the early 1900s (this property and adjoining Schocken Hill, now the Sonoma Overlook Trail, essentially paved the streets of San Francisco at the time), and there is a quarry “divot” in the hill above that collects rainwater and funnels it out to the trail. Being essentially bedrock, the water has nowhere to go but out and down.
What the trail needed is what’s called an “armored swale,” which is essentially a channel cut into the trail that is protected by a floor of rocks to prevent erosion. I had been waiting for rain to soften the soil, as we would first need to excavate the existing rocks and in summer the ground is like concrete. It rained yesterday, so the soil was going to be about as soft as it was going to get. Also, since I knew that an “atmospheric river” was set to dump several inches of rain in a matter of a few days, now was the time to act.
So Jessica and I went out today and built it. We first needed to excavate a channel across the trail, then place stones to protect from erosion, and fill in gravel and soil around the stones. Do your worst, atmospheric river, we’re ready for you!
