Sierra Nevada starter map

Sierra Nevada: 3 regions on their counties, each in the colour it wears in the list below.

Three regions on county lines along California's Sierra: the northern counties above Tahoe, the central Sierra and the southern Sierra.

In the editor each region takes a level with one click. When one region needs more detail, split it into its counties and set them one by one; merge it back when they agree.
