Retreats on Mauna Kea?

[TomK]

unless all camping sites are defined as retreats

I organized, and hosted, a photograph retreat on Mauna Kea the week leading up to July 11, 1991 in which a dozen world class photographers, and their various teams and other guests, gathered to do photographic sessions on and around Mauna Kea, culminating in being on the summit for the total eclipse on that date.

Can you provide a link to photos from your colleagues at the summit of Mauna Kea that day? Thanks.
