A unique microclimate runs through the Geology Trail, and it's home to more life than most people realize.Come find out what's been hiding in plain sight.On Saturday, April 25, from 8–10 AM, join Robert Doyal and Tracey Burke, Texas Master Naturalists and iNaturalist Ambassadors, for a morning nature walk where we'll use the free iNaturalist app to spot, photograph, and identify whatever we find — plants, insects, birds, and the stuff you walk right past every day without noticing.No experience needed. If you can point a phone camera at a bug, you're qualified.The Big PictureThis walk is part of the City Nature Challenge, a worldwide event where people in hundreds of cities spend four days discovering and documenting the wildlife around them. Everything you photograph becomes part of a global biodiversity dataset — and helps scientists better understand what lives right here across our 12-county San Antonio Metro Area. That beetle clinging to a piece of bark? That's data. The lichen creeping across the exposed rock? That's a contribution. You're not just going for a walk — you're mapping what lives here.DetailsSaturday, April 25 · 8:00–10:00 AMPhil Hardberger Park — Voelcker Homestead Trailhead (1021 Voelcker Lane)Easy walkingRegistration is required — please RSVP through Eventbrite to save your spot.Before you arriveDownload the iNaturalist app and create a free account — it takes about a minute and means we can start exploring right away.What to knowPlease arrive by 7:45 AMBring water and sunscreenWear closed-toed shoes and dress for the weatherGreat for adults and older kids (14+)Please leave pets at homePark at the Voelcker Homestead Trailhead lotThis event is entirely outside and will be cancelled if there is inclement weather or unsafe conditions.
