Through short time after that J. Gregg has published the classical description trading karavannogo ways to Santa Fe under the name ' Trade of prairies '. Between 1831 and 1839 it has made eight trips on the West and long time has lived, in Mexico.

Despite all it, news about the West remained rather poor and in some respects absolutely doubtful. In 1824 the dealer Jam Bridzher has opened the Big Salty lake, but correct representation about hydrography of the Big Pool then yet was not, and there was an assumption that there is a big river Buenaventura which flows from Rocky mountains in the western direction and runs into Pacific ocean at San Francisco. There was no clear representation and about mountain areas. Something for picture clearing was given by work of captain Bonvillja (1832 1836) . Fur trade was its main purpose, but at it were both scientifically-geographical interests and projects. The first year he has devoted to travel through Southern pass to the river Green, to sources of the river Snake and to the river Solmon where it has wintered. During this period he has examined big lavovuju plain between the rivers Solmon and Snake. Next year it has sent assistant Walker on research of the Big Salty lake and neighbouring territory. It was not possible to Walker as it is necessary to execute commission Bonvillja, but it has visited on Humboldt's river, has proceeded on it to ' sinkov ', has crossed Sierra-Nevada and left to Montereju. Back it has returned round a southern extremity Sierra-Nevada and yes lee on trading karavannomu ways Santa-Fe-Kalifornija, to the river Ber. In the meantime Bonvill, in turn, has made the big work in the north. In the beginning it investigated territory round river Yellowstone sources, has visited valleys of the rivers Uind, Green and Suituoter but to pass through mountains Uind-River has not managed. In the winter 1833-1834 It has visited on the river Snake, has crossed Blue mountains and left to Colombia at Valla-Valla. In the summer of 1834 it has visited again to Colombia, and next year has come back home. Though cards Bonvillja also did not differ the big accuracy, the hydrographic system of territory to the West from Rocky mountains on them has been represented correctly.
