El Desemboque (Seri: Haxöl Iihom) is a town located 376 km from Hermosillo on the shore of Gulf of California in the Mexican state of Sonora; coordinates N 29° 30' 13", W 112° 23' 43".
Their oral history has them living as far north as present day Puerto Penasco which was also an O'Odham settlement as well as present-day Bahia Kino and Isla Tiburon (shark island).
At some point, probably in the 1930s, it was moved to its current location which offered better protection for the developing fleet of small skiffs (local Spanish, pangas) that the Seris used for commercial fishing.
After the construction of the highway linking Bahía de Kino to Hermosillo by the year 1953 (Sonora State Highway 100), the small community of Punta Chueca to the south (and closer to Bahía de Kino) rose in prominence to become the focal point of Seri political life.
[citation needed] El Desemboque remains a thriving community with commercial fishing and artisanal crafts as the two major economic activities.
The village is home to a primary school, cultural center and small clinic as well as one of Mexico's oldest fishing cooperatives.
