Lassen Peak trip

Tue Aug 02, 2011 6:54 am

So, I drove the Leaf to Lassen Park on Sunday.

Image

Still quite a lot of snow at 8,500 ft. The trail to the Peak was partially closed. It's only open intermittently while being reconstructed. I took a very nice hike to Echo lake, instead.

You probably wouldn't be able reach the Park entrance From Redding via hwy 44 on a single charge (about 47 miles and 8,000 ft of ascent) (edit-should read: about 47 miles and 5000 feet of ascent, then another 3,000 feet and 21 miles to the peak trail parking lot, where the photo was taken) and there are currently no (official) charge points in the Park. I would suggest a recharge at Shingletown, where there are several likely RV parks. Mt Lassen KOA offers a $10 flat Fee 240 V recharge, if you have a portable EVSE. The Managers, Al and Jean Butzine, are very receptive to EV visits, especially if combined with campsite or cabin rentals, so you might want to overnight. From Shingletown, (4000 ft) you can make it the last 30-something miles to the summit with 3-4 bars left, and return to Redding on the same charge with a few bars left, if you limit your speed to 50-55 mph both ways.

My trip from my home (near Oak Run, 2,000 ft altitude) was a little longer, 144.4 miles round trip, about 11,000 ft. total and 6500 ft. net ascent and descent. I recharged from 3 to 12 bars near Shingletown, at a Friend's cabin on the way up. I'd hoped to make the 94.5 miles to the peak and back home on this one charge, taking advantage of the 2,000 ft net descent, but it became clear I'd need to drive well under 50 mph to do so, so I stopped on the way back, charged from 4 to 8 bars, and still had 3 when I got home.

From this and other long climbs and descents I've made, my rule of thumb is now each 800 ft of ascent consumes about one bar, and each descent of 1,000 ft adds one bar. This is assuming road and traffic conditions permit Regen to do most of the braking, and you have 10 bars or less of charge, so full regen is available.

I would not have thought near 80% recovery of ascent energy (by both "coasting" and regen) likely in real-world use on extreme grades, but that's what I'm seeing, and it seems other recent hill climb threads reflect the same experience.

That's good data. Thanks.

Thanks for the post! (I just noticed it.) Looks like there is a bit less snow than when we were there in mid-June of this year:

We were truly impressed by Lassen park and intend to return within a year or two. Thanks for documenting your LEAF experience there.

And I just noticed an error in my post (about 47 miles and 8,000 ft. of ascent) should read (about 47 miles and 5000 feet of ascent).

It's another 3,000 feet and twenty-something miles to the peak parking lot, where the photo was taken.

The road is rarely cleared of snow before July, and was opened this heavy-snow year only at the end of July.

Lassen is a great place, and one of the least-visited National Parks, even though it's only an hour drive from I-5.

Thank you for the clarification, though I sort of figured that's what you meant since the park entrances are below 6000 feet elevation.

I wonder if you might be able to charge at the campground near the North entrance, either at an RV campsite or a park building. (We stayed there, and shopped for supplies in Shingletown.) I know you were trying to get permission to charge at Lassen. Did you get anywhere with that?

Despite my repeated inquiries, Joshua Tree National Park would not agree to let me plug in the LEAF anywhere, even at 120 V and even if I made a donation (see viewtopic.php?f=7&t=3025). I'm not sure if that's because of Federal policies (see viewtopic.php?f=7&t=2667#p59459), or just because the Park management didn't want one more thing to worry about. It would be nice if the Lassen management proves to be more accommodating.

Update-

I never made it back to the Lassen Peak trailhead in my LEAF last Summer, but did visit Lassen park by taking the longer highway 299 to 89 to 44 route, looping around the Thousand Lakes Wilderness. There is an RV park at Hat Creek for L2 (See recargo for details) if anyone wants to drive this route.

Below is my trip profile on highway 44 to the Peak trailhead lot. If you take Highway 44 from Redding, you'll pick up this profile at ~mile 20 miles, at the intersection of highway 44 and "old highway 44". There are several RV parks at ~mile 40 on this profile, including the Shingletown KOA. They are also at ~40 miles on this profile (but more like ~3,800 ft of total and ~3500 ft net ascent) from Redding.

Image

From the trailhead it's one of Gorp's "top ten" day hikes to the Peak:


4. Lassen Peak

5-mile circuit in Lassen Volcanic National Park , CA
Almost 65 years to the day before Mount St. Helens blew its top, Lassen Peak, the southernmost active volcano in the Cascades, exploded violently and spewed ash that landed 200 miles to the east. Today, the ninth-highest volcano in the Cascades is dormant, but the scent of sulfur still seeps from its cracks. It also makes for one of the most accessible summit day hikes in the Pacific Northwest. A short-but-steep five-mile out-and-back trip culminates with spectacular 10,457-foot-high views into the destruction from almost a century ago. The trail begins at a parking area at about 8,500 feet up the volcano. Follow a series of switchbacks and steep pitches up the southeastern ridge for about 2,000 vertical feet to reach the airy summit. From there, find a rock on which to kick back and take in the views of cinder cones and the remnants of some 30 volcanic domes that make up the park. The peak can get more snow than many other surrounding areas—upwards of 40 feet—meaning the main road into the park can be closed much of the year. It's best to go in mid-July.

I was lucky to get there (BY ICEV) last August (on one of the few days the trail was open last summer) and walked to the top.

Love it! Thanks for the report. We hiked the Lassen Peak trail last summer, but had to turn around about halfway to the summit due to the trail closure. It was still an awesome little hike, though. Of course, we did not have the pleasure of using the LEAF; our conveyance was the Prius.

Re: Lassen Peak trip

Thu Jun 27, 2013 7:30 pm

Almost two years after my first trip to Lassen NP in my LEAF, I made it back to the Peak.

Lassen was great, as always, especially since the temperatures on Valley floor that day were reported to be as high as 113 F! I had lunch at the peak, then back-tracked to ~6,700 ft. (at the end of trip 4, at point D) to find a snow-free trail for a hike.

I think my earlier inexperience with large ascents and descents (must be pretty close to 13,000 ft. on this route) may have made the trip seem harder than it was, as I described it two years ago. Redding to the Peak and back is certainly manageable with one ~12 to 15 kWh recharge at ~4,000 ft elevation, as long as you take reasonable measures to drive efficiently (slowly!) on the trip.

I'd encourage everyone driving through the North State to visit one of the most under-appreciated National Parks, and one relatively easy to access (with a portable EVSE) in a BEV.

The Peak trail is scheduled to be open over this Fourth of July Weekend, BTW, offering one of the few opportunities to climb the Peak, before the trail project is completed in 2015.

I had a much easier time with the range-planning this time, having a lot more experience with large ascents and descents, having the ability to read the nav screen m/kWh and knowing my remaining kWh to the LBW and VLBW to within a few hundred Wh of accuracy. I still haven't figured out any way to use the Battery app to get usefully accurate Wh use reporting. For example, the app reported ~250 Wh use while I was sparked at the Peak lot!

Benefiting from the ~2,000 ft. net descent, I did the last 109.3 miles of the 154.3 mile trip from a single recharge to "100%" at the 45 mile, ~4000 ft. elevation point, I got to the Peak and back home (using only one charge bar for the 77 mile ~6,400 ft. net descent from the Peak!) with two bars left, and probably ~2 (nominal, Dash/nav screen/CarWings) kWh left before the VLBW, at the end of the trip.

Next time, I won't wait for the slow top-off to "100%" at the recharge.



Back at the Peak trail lot, on 6-8-13. Drought watch- there is not much more snow than there was on my first trip ~7/30 of 2011.

Here is my route:

Excluding the first ~.3 miles and ~150 ft of descent, and the same distance and ascent on the trip end, Which Google will not map.

Here is the elevation profile for that route:

An update.

Lassen NP is currently considering putting in charging facilities!

Amanda Sweeney is LVNP's contact for the project, so if you'd like to make comments or suggestions, you can reach her at:

Amanda_sweeney@nps.gov

530-595-6134

I believe that none of Lassen's campgrounds have power. But LNVP is, IMO, ideally suited for L2 installations, as there are low elevation visitor centers with electric service, at both ends of Highway 89, which crosses the park from North to South.

At the North (main?) Entrance there are hiking trails and an interpretive center at Manzanita Lake, which would give you plenty to do, while waiting for the recharge to get to the higher elevation attractions.

If you have a Park near you, that you would like to see install charge sites, you might want to look at this old thread:
