I have this penciled in for Earth Science Week 10/8-14/23) and International Earthcaching Day(s) it seems to still be a simple GC Event Cache, not an Earthcahce per se. May work on listing an Earthcache nearby to coincide with that weekends event.
Part of the Planetarium presentation would be a short film (24 minutes) on "Super Volcanos". While I would like this Event to qualify for an Earthcache, I don't think it does. Oh well.
