City Nature Challenge. 12-Mile Coulee, Tuscany. Plants. Hundreds of Townsendias. From Stoney Tr NW, go W on Tuscany Blvd to Tuscany Way Turn S (left) and go 1.9kms. The road becomes Tuscany Ravine Road. Park in open area under power line. Here, carpool (due to limited parking.) and go another 1/4km further S. Walk down a fairly long steep hill (probably not for anyone with walking difficulty). Leader, Karel Bergmann, 403-285-2380.
