Matanzas River Marsh

The picture below of the Matanzas River comes from the west end of Dondanville Road in Saint Augustine, Florida, and demonstrates the diversity of waterways, with this beautiful marsh located just blocks away from sandy beaches.  This is part of the Intracoastal Waterway, a 3,000-mile stretch of mostly inland waterways beginning in Boston, Massachusetts, going around the southern tip of Florida and continuing along the Gulf of Mexico to Brownsville, Texas.

Matanzas translates to "massacre" or "killings" and in this case relates to the murder of several hundred shipwrecked French Huguenots by Spanish forces led by Pedro Menéndez de Avilés way back in 1565.
