From Jason Gerhardt of Real Earth Design:
Boulder Keyline Design Course – August 16th &17th
Learn the water-saving and soil-building process of keyline design from the leading practitioner of the subject in the US, Owen Hablutzel. This course is most applicable to land owners and farmers/ranchers, but will be of interest to all permaculture thinkers out there. It will take place at the beautiful McCauley Farm. I hope to see you there!
