Rancho Cañada de Raymundo was a 12,545-acre (50.77 km2) Mexican land grant in present-day San Mateo County, California given August 4, 1840 to Raimundo (also known as Raymundo), a native of Baja California, who was sent out by the padres of Mission Santa Clara to capture runaway Mission Indians in 1797. On the 1856 Rancho de las Pulgas and 1868 Easton maps, the valley of Laguna Creek was referred to as the Cañada de Raymundo. Laguna Creek was also alternatively known as Cañada Raimundo Creek. In 1841 Rancho Cañada de Raymundo was granted to John Coppinger by Governor Juan Alvarado for helping in the revolt led by Alvarado against the Mexican authorities in Monterey. The two and one half league long by three-quarter league wide grant consisted the eastern slopes and valleys in the present-day Woodside area. The grant began at Alambique Creek, the north border of Rancho Corte de Madera, and extended north to Rancho Feliz. Rancho Cañada de Raymundo was bounded on the east by Rancho de las Pulgas. The rancho contained Laguna Grande (now Upper Crystal Springs Reservoir), then a natural lake that was the campsite of the Portolà expedition on November 5, 1769, and was bisected by Laguna Creek, which flowed from southeast to northwest through the lake on its way to San Mateo Creek.
