[Utah-astronomy] Bryce Canyon Astronomy Festival

Does anyone know the dates for the Bryce Canyon Astronomy Festival? According to the official Bryce Canyon Internet site, there's a brief sentence saying it's from June 21-24 but if you scroll down the page it has the 2016 schedule. It didn't help much when I looked at the Salt Lake Astronomical Society's  (SLAS) page and had it listed for only June 21 - 22.
