Phil,
Thanks. I know -- I got *very* lucky this year. My luck continued into the second half of my Sierra adventure -- I hiked up the North Lake access road and over Piute Pass about a week before the mudslide. Of course, I spent many a quality hour sitting in my tent during the long rains that contributed to it. That TR is in preparation... I have to read up on the Lions fire some more -- it seems like it died down for a while and then flared back up? This is the one south of the Minarets, yes? I was on the Mammoth webcams several times a day before my trip and was relieved when things cleared up right before my start date.

That was part of one of my favorite layover dayhikes of all time: a loop that began at Blue Lakes went over Foerster, then to the Lyell Fork, then over Electra, then back.
Thanks for the note. I know from reading some of your previous posts you are an avid fisherperson, so your appreciation of the Lyell Fork drainage is high praise indeed. I hope to get back there some day when the sun shines more reliably, and I wouldn't mind trying my talus-hopping boots at one of those other cross-country passes that you must have used. Did you return to Blue Lake over Old Bones Pass?


So here's one that I am going to ask my geology colleagues the next time we are out for Friday beers: what's a quartzite (I think) outcropping like this doing in a place like this on the south slopes of Foerster Peak near Blue Lake Pass?

The contrast to what surrounds it is striking to me, but what the heck do I know? Everything else around seems to be the usual granitic rocks, so to the untrained civilian eye this is way out of place. Do you think this a remnant of all the other top layers that have eroded away? Or is it the result of some more complex geologic event? Any undergraduate level explanations would be appreciated. :nod:

Hi Dennis,

Regarding the route back from the Lyell Fork to Blue Lakes what I did was to climb right over the top of Electra Pk which meant ascending Electra's W ridge and descending the ESE ridge. I then "wrapped around the corner" at approx 10400 to descend into Bench Cyn (at about the 9700 level) and heading back upstream (W) to Blue Lakes. The entire route from Blue Lake to Foerster then down to the saddle then into the Lyell Fork then over Electra was done at the class 1 to 2 level except for a smidge of class 3 near the top of Electra's E ridge. This would have been pretty easy but I was climbing more or less one-handed because I had broken two fingers on my left hand the day before while dayhiking to Harriet Lakes.

Quartzite among granitics. This can be explained in several ways. First is that quartzite is locally present in the metamorphic rocks intruded by the Sierran granitic rocks, so it would be possible to have a small wedge of the stuff in otherwise completely granitic rock. Another possibility is that the rock is very pale and quartz rich but not necessarily a quartzite. It may be a very quartz-rich dike or it may be a quartz vein.
Since my fishing (etc.) website is still down, you can be distracted by geology stuff at: http://www.fresnostate.edu/csm/ees/facu ... ayshi.html" onclick="window.open(this.href);return false;

Now that I look at the topo more closely, that does seem like a good alternate to Old Bones Pass at higher elevation. Don't know about the one-handed technique, though.

Thanks for the potential explanations -- it adds a dimension to that part of my hike.

And interesting trail report indeed. You went over some of the territory on the Lyell fork that was part of the HST meet-up two years ago, and so I saw a few glimpses of familiar terrain. But a report with Tolkien and guinea pigs and the Lyell Fork is truly one-of-a-kind!

Thanks for the note. Family matters definitely help add to the variety. I'd like to make it to a HST meet-up sometime -- have to remember to monitor the forums for details.

Sorry for the late reply -- speaking of family, we are on a monster road trip and retreating homeward and have our first internet for five days. The girls are curiously quiet right now. ;) We experienced lots of haze in Glacier NP, Mt St Helens National Volcanic Monument, and the Sawtooth Mtns, which was disappointing. We didn't even bother with Crater Lake NP. But Devils Tower National Monument was superb this morning, and I predict good things at Pipestone National Monument in MN tomorrow morning.
