At the CVO Sediment lab I analyze suspended sediment samples from many rivers in the USA.  

Because we are a Volcano Observatory, I have had the opportunity to analyze samples of volcanic ash and debris.  Not only from our own Mt. St. Helens but, from other volcanos around the Ring of Fire. 

I am grateful for the help of the labs robot to tare and gross the hundreds of crucibles we use in our analyses.
