Summary: Sierran rivers that discharge to the Lahontan basin have much lower (~ 4.5 per mill) d87Sr values than the Humboldt River
which drains northeastern Nevada. The d87Sr values of tufas deposited during the last lake cycle were used to determine
when Humboldt derived Sr entered the Pyramid Lake subbasin. Prior to ~15,000 yr B.P., the Humboldt River flowed to the Smoke
Creek-Black Rock Desert subbasin. During the recession of Lake Lahontan, the Humboldt River diverted to the Carson Desert
subbasin. This study has demonstrated that 87Sr can be used to determine drainage histories of multi-basin lake systems if
the d87Sr values of rivers that discharge to the basins are sufficiently different.
