Glare is fine, just wear sunnies. The flare is no problem in clear skies - and don't trust the RADALT.
Gaunty - Generally a regular circuit is flown, although sometimes at 500' with a closer then usual downwind to inspect the tracks if doing multiple drags before committing to landing. As for glideslope guidance: time the circuit in the same way as one would at say Eucla at 0330 local....
A landing area like this is great. Great definition for landing and orientation. Without the mountains and with BKN Cirrus or worse, there are similarities with the black hole approach except that you can't rely on a visual in the last 100 feet in your landing lights... For that reason, it's usually best avoided.
When I did some skiflying in an Auster in overcast skies, you just set it up for touchdown with a nice slow rate of descent and wait for the bump. In deep snow it's like landing on a doona!
