apparent that the areas designated on the map as Alamedan and Huchiun
contained a heavy concentration of inhabited spots. This conclusion is
in conformity with the waterfront habitat and the probable large food
reserves. Along the strait and the southern shore of Suisun Bay the
known habitation mounds are less numerous, but there are enough to
indicate a reasonably high population density. This area on the map has
been ascribed to Karquin.

Through the generally hilly interior of Alameda and Contra Costa
counties there are but two areas of sizable extent in which preconquest
village sites occur with relative frequency. One is the Lafayette-Walnut
Creek-Danville region and the other the Livermore Valley, west to
Pleasanton and Dublin. These provinces were inhabited in the late
eighteenth century by the Saklan and Seunen respectively, and are so
designated on the map. Indeed, the correspondence between archaeological
sites and the occurrence of rancherias in early colonial times is
remarkably close. The conclusion is permissible that the pattern of
occupancy found by the Spaniards had been established long previously
and was fully stabilized at the time of their arrival. This condition
in turn argues a mature balance between the natural environment and the
indigenous population.
