In a study published in American Antiquity, Dr. David Madsen and his colleagues address the proposition that the lower Lahontan drainage basin (LLDB), located in the Intermountain West, is "unique" for the use of caves and rock shelters as burial locations. They found that, compared with the Bonneville Basin (BB), the Great Basin's other major lake basin, the LLDB is not unique, and burial beyond it is neither rare nor uncommon.
