We really like the giant salmon sculpture exploding out of the concrete and the water feature next to it so we put a geocache nearby. Since Santa Rosa Creek used to have more salmon in it before the city did flood protection, in the 1990's, the city got some help from a local family to totally redo the waterway to support the declining salmon population. This bridge over the creek shows you the work they did and hopefully some salmon certain times of year...
Be careful and try not to drop the cache or your phone!
