Air Quality Walk with GASP

Join staff from ALT and GASP (Group Against Smog & Pollution) for an air quality hike at Churchill Valley Greenway. We’ll discuss how past land use affected this area. We’ll also explore how climate affects seasonal changes and look for sensitive, bio-indicative species of air quality such as lichens, amphibians and plants. Events run rain or shine. No walk ins will be permitted.   TICKETS
