Arroyo "Not so Seco"

The normally sleepy Arroyo Seco stream that runs by the JPL Lab in Northwest Pasadena/La Canada is bursting with water after last week's storms. I went there the weekend before the storms and it was nowhere near this size. For a comparison, during that weekend I saw a parent let his two sons walk their bikes across the stream in the area pictured below. It looked totally safe. Now, they would be swept away

Here is a comparison of what the stream looks like in autumn. I hadn't started going there by last fall, but I imagine it was even drier.
