I don't have any recent pictures either, but it's worth noting that if you went in Sept 2020, the lake was close to 3600, or about 40 feet higher than today. One of the nice things about Face Canyon is that if you've got a kayak, are willing to hike, and the lake levels are low (like now), you can get some really nice access well beyond what you could do in a speedboat. It's a pretty awesome hike into some great narrows... way better than if the lake were say, above 3610. If you can get in there, this is the prime time to see Face Canyon.
As for campsites, you ought to be able to find something near the mouth of Face Canyon, especially on the west side toward the entrance...
Here's my past notes on beaches and hiking in Face Canyon, some of which doesn't apply now because we are at such low lake levels:
Beaches. More campsites at higher lake levels, especially above 3650. Nice beach in righthand (west side) cove about 2.5 miles up the canyon at lake level 3640-3660. Most of the best sites in general are within the first two miles of the canyon, and typically in the coves on the right, or west side, of the canyon. Some sites are possible in these areas from 3600 and higher, but there are fewer sites as the lake level drops and coves become less accessible. Few if any sites in the entire canyon below 3590.
Hiking and Access. Face Canyon features an excellent convoluted slot, but it is only accessible from a boat at certain lake levels. The slot may require swimming depending on whether there was a recent flood, and some climbing may be needed. The slot disappears underwater above 3610 or so. The best boat access is when the lake is at 3600-3605. At that point, it’s wide enough for a speedboat to get to the end and beach, with a hike to a slot about 0.4-0.5 mile beyond the landing site. But if the lake is lower, especially below 3590, there is a pinch point of about 5 feet in width that will stop a speedboat. But kayak access is possible at these lower levels, with the hike beyond as described above. When the lake is between 3620 and 3650, it may be possible to access the end of the canyon with a speedboat, but there is no landing and the slot is inundated, so no hiking is possible. When the lake is full, a landing may be possible beyond the slot area (not verified), but the slot is inundated. The canyon narrows toward the end, making boat access and landing potentially difficult.
There is possible access to the end with a skiboat when lake levels are below 3610, otherwise it gets too narrow. Kayaks or small fishing boats may access to the end at most lake levels. This is an excellent slot canyon, but the best part of the slot disappears when the lake is above 3608.
