The circular "trench" around the central hemisphere doesn't look like any sort of cooling or weathering joint I know or can explain. I would guess that the cutting of the "trench" and rounding of the hemisphere was the work of humans.Wandering Daisy wrote: ↑Fri Jul 12, 2024 9:11 am GB- what do you think is the odd rock feature shown on the third photo? Is it natural or maybe a human artifact?
Regarding the fish in Lewis Lakes they had medium sized brookies (topping out at around 11") when Judy and I fished them in 1991. That was during the air drop era and I think the lakes were in fact receiving regular brookie fingerlings then, just as Ridge, Sardella, and Iceland were receiving golden fingerlings (we caught goldens there). Since cessation of air drops, brookie populations have persisted with robust natural reproduction in the Lewis Lakes and I think Middle may produce somewhat bigger fish than Judy and I encountered, based on CDFW gillnet data (may top out in foot-long range). Of the golden lakes, I think Sardella and Iceland (which once grew some pretty large fish) are now fishless, but goldens persist in Ridge.
Regarding black flies, I don't recall having been actually bitten by black flies in the Sierra, whereas I have always been a mosquito target, until last year when I took a beating from some sort of fly in addition to mosquitoes while bushwhacking between Lake Vernon and Branigan Lake. They were pretty itchy, perhaps a bit more so than the mosquito bites, but they were nowhere near as vicious as the black flies that harass folks on the East Coast (not sure if it's entire East Coast but certainly the NE). The "other" type of black fly was public enemy no.1 in my 2022 and 2023 Newfoundland fieldwork and that sort of black fly attacks very differently than the flies of the Sierra. The Sierra flies attack exposed skin and bite through thinner and close-fitting clothing much as mosquitoes do, but the nasty ones that attacked me in Newfoundland attack exposed skin but commonly also crawl beneath clothing to bite in places they could not through clothing. Their bites didn't seem to swell up as much as the mosquito bites (got a lot of those in Newfoundland, too), at least for me, but these bright red spots would develop and they were super itchy--poison oak level itchy (to put it in a field geologist's comparative itch scale).
