What is unusual about the rivers and streams that flow into the great basin?

The rivers and streams that flow into the Great Basin are unusual because they are endorheic, meaning they do not flow into an ocean or sea. Instead, they drain into lakes or evaporate, leading to a closed hydrological system. This results in high evaporation rates and high salinity levels in the lakes, as minerals accumulate without being flushed away. The Great Basin's unique geography and climate contribute to this distinctive water behavior.
