Four years at the weep
CrisThis post is a working roster of my visits to our weep site just north of Alviso and the aerial photographs taken there. Wayne and I are working with Dan Rademacher at Bay Nature on an article describing our unassuming weep. This list is a means of putting a variety of images and brief observations on the virtual table.
The roster is organized in chronological order. For each visit I am including representative thumbnails, which link to larger images on Flickr (which link yet again to even larger images on Flickr via “all sizes”). In many cases, to get a good sense of the image you will have to visit the larger version. Below the thumbnails I have made a link that will pull up a slightly larger set of images from that session (generally 6 – 12).
