1770 - Plano del Tondeadero o Surgidero de la Bahia y Puerto de Monterrey - situado por 36 grados y 40 minutos de latitud Norte

A detailed survey by Miguel Constanzó of the Port of Monterrey in which he identifies landmarks and potential locations for anchoring ships, including: Point Pinos, sheltered anchorage (except from the north-northwest winds), the site for the Mission and Presidio de San Carlos, several lagoons and an estuary that was filled by the tide. This is one of at least four Constanzó maps or plans resulting from the Spanish exploration of the coastline of Alta California between 1769 and 1770.https://digitalcommons.csumb.edu/hornbeck_cgb_4/1025/thumbnail.jp
