I saw this is an email from Zach Weiss of Elemental Ecosystems. He was trained and certified by Sepp Holzer. Not sure if it has been posted here. Here is the text from the e-mail:
We are moving forward with organizing the Elemental Ecosystems tryout. Our goal in hosting this event is to identify those that would be a good fit to work with our project crew in the future. This event will be a week-long tryout for our team to work with those interested in taking on our type of water restoration work for their livelihoods. It will be a test period to identify those who are a good fit.
The tryout will take place in early October 2019, in Southeastern Montana.
If you are interested, please contact us through our website, elementalecosystems.com, and we will send you more information.
