    Veteran Acres - Sterne Woods (Oakwoods Lodge) by Far Syed

    We managed to find the ice whole opening, to collect the sample, the water was really cold, so it seems like the chloride content increased! It was chilly out, but movement helped ☺️

    Timber Ridge Forest Preserve by Andy Culbertson

    The weather was warmer and the trail easy to walk this time. Photos: - The trail and bridge looking west. - Wide-angle view of creek from the bridge looking north. - A closer view of some mallards on the creek. - A view of the small waterfall under the western end of the bridge. - The waterfall with my sample bucket just above it. I sampled from here this time because it was easier to capture the water. - The test strip reading.
