Sacaton Field Trip By Harvey Jong |
||
|
Even though eriochalcite is water soluble, samples of the newly-identified Arizona mineral were still available. Other noteworthy finds included a cluster of zoned barites, a boulder of fluorescent/phosphorescent calcite, and an unknown mineral that rapidly changes color from a dark- to light-blue when a fresh surface is exposed. |

The Asarco Sacaton mine near Casa Grande was the site of this year's post-Symposium field trip. The turn-out was relatively light as rainy conditions from the previous day may have discouraged some attendees. Weather on the day of the trip was, however, sunny with a few clouds and a slight breeze. |
