Falls at Crocket Gardens – Knight Spring at Crocket Garden is one of the major springs along the North San Gabriel River. After emerging from a cleft in a limestone bluff, the spring runs a short distance before plunging over a cliff into Lake Georgetown. The spring and falls can be seen by hiking the San Gabriel River Trail from the Cedar Breaks Trail head.
Wildflowers Along the River – Wildflowers are abundant throughout the San Gabriel 
River valley. My favorite spots are along the North San Gabriel between Georgetown and Lake Georgetown and in Berry Springs Park. Among many spectacular flowers is the day flower (right) which grows in shady spots along the river.
Fall Color Along the San Gabriel River Trail – Rounding a curve in the river trail, my breath is taken away by the brilliant autumn colors—the yellow of cedar elms, scarlet of red oaks, and orange of sycamores—on a cool fall morning.
Alligator Gar – Peering down from a Farm to Market Road bridge that crosses the upper North San Gabriel River, I catch sight of a half dozen 6 ft long alligator gar, slowly nosing through the shallow water below like miniature submarines.
Waterfall on the North San 
Gabriel – One of my favorite sights is water cascading over this low water dam on the North San Gabriel River.
Dinosaur Tracks in the San Gabriel – Scientifically, one of the most spectacular sights along the San Gabriel River is tracks left by dinosaurs that walked the river banks 100 million years ago.
Georgetown Salamanders – Nothing makes my day more than turning over a rock in a spring along the San Gabriel River and catching sight of a Georgetown salamander.
Snowfall on the San Gabriel – An unexpected January snowfall blankets the riverside 
with a soft white cover, through which peak the tracks of numerous small mammals.
Golden Checked Warbler – This beautiful and endangered species, easily recognized by the bright yellow spots on the sides of its head, is common in Russell Park and Taylor Ray Hollow and other spots around Lake Georgetown.
River Bluffs – Among the most common and yet remarkably beautiful sights along the San Gabriel are the limestone bluffs that often tower 50 feet or more above deep water on a curve of the river.
