Information About the Palmer Divide

  • Cities and towns within the Palmer Divide include
    • Castle Rock, Franktown, Elizabeth, Kiowa, Monument, Black Forest, Sedalia and Palmer Lake.
  • Areas of the Denver metro along C-470 from Chatfield to Interstate 25, and along E-470 from Interstate 25 to Smoky Hill Road are on the extreme northern fringe of the Palmer Divide.
  • The elevation along the divide varies between about 6,000 and 7,887 feet (1,829 and 2,404 m), with the high point being Bald Mountain in southern Douglas County. 
    • This peak can be seen from I-25 just northeast of Monument Hill.
  • This uplifted area causes a slight increase in precipitation from the rest of eastern Colorado, resulting in the presence of the Black Forest, a peninsula of trees surrounded by dryer grassland plains.
  • The Palmer Divide is also implicated in enhanced landspout and tornado activity to the east of Denver in the Denver convergence vorticity zone (DCVZ).
