Walk to School on World Wetlands Day

Students of the GISSV San Francisco campus honored the UN-designated World Wetlands Day on February 2.

Report by San Francisco Kibili parent Beate Antonich, who lead the walk

Seven GISSV San Francisco students from kindergarten to grade 5 voluntarily participated in our monthly walk-to-school day. They took a closer look at the Presidio's Tennessee Hollow Watershed while walking the Ecology Trail.

The group started off at Inspiration Point. From this peak, they took time to view and observe this protected area. They were asked to imagine how the water of a heavy rainstorm would flow down on this landscape. Using markers, they drew their answers on a photo of the area, noting that gravity would lead the water to flow down the hillside leading to the San Francisco Bay. They also learned that the water collected in this watershed can take three years to reach the San Francisco Bay, thereby providing the land with water even during dry or drought seasons.


Next, the students walked the Presidio Ecology Trail and identified areas where water naturally collects. They stopped at a flat land area and observed the soil being moister as well as different grass plants in this area compared to other parts of the trail.

Continuing on the trail, students observed several water stream paths, noting how deep their traces occur in the trail.

Students also viewed and heard water flowing out of the hillside and several pipes navigating the water.


They noticed some pipes with water flows are hidden in the landscape.


Students were informed that a watershed is an area of land that catches rain and drains into a body of water.

For interested parents, Tennessee Hollow is the Presidio's largest watershed, encompassing 20 percent of the park.
