  • Old Monarch Pass at an elevation of 11,375′ was actually the second Monarch Pass.
  • It opened in 1921, and was engineered for ‘Automobiles’.
  • The original pass was a toll-road which opened in 1880.
  • It was traveled by wagon or stagecoach, and crosses what is now the Monarch Ski Area.
  • Today the first Pass is referred to as “Old Old Monarch Pass”.
  • Present-day Monarch Pass at an elevation of 11,312′ was opened in 1939.
  • Each new pass was re-routed to reduce sharp curves, increase safety, and shorten the distance.

The first two Monarch Passes were closed in winter, which isolated Gunnison.

  • By the late 1930’s, there was a need to have a pass which was open year-round.
  • In order to reduce the numerous hairpin curves of Old Monarch Pass and build the road in the sunniest locations, one or two local historic cemeteries were destroyed.
  • Also, the state highway engineer at the time, Charles Vail, renamed the pass “Vail Pass” after himself.
  • Local residents were outraged, and tore down all the new “Vail Pass” signs.
  • The governor finally stepped in and reinstated the name “Monarch Pass”.

  • The Old, Old Monarch Pass toll road was a stagecoach road which started as the mining boom exploded in the upper South Arkansas valley in the late 1870’s.
  • The road provided access to White Pine and the Tomichi mining areas as well as to the Gunnison country.
  • It was opened in 1880, and in 1881 it became a toll stagecoach road operated by the famous Barlow and Sanderson stage line.

The D&RGW did not go over Monarch Pass, but up to a Limestone mine on Monarch Pass.

  • It had been converted to Standard Gauge and ran until 1985.
  • The old Monarch Branch of the D&RGW to the Monarch mine between Maysville and Garfield is a fun, little known ride.

Old Old Monarch Pass

  • The old old road ran up the South Arkansas valley through Maysville, Arbourville, Garfield, Monarch and Monarch Park.
  • From the upper end of Monarch Park, the road took a series of steep, sharp switchbacks and climbed up from the valley floor.
  • Through what became the Monarch Mountain Ski area before crossing the Continental Divide at the low point on the Great Divide ski run, at an elevation of 11,523′.
  • The current ski area maintenance road from the north end of the ski area parking lot follows the old, old road to the Divide.

Blacksage Pass Summit

There was a toll gate at Maysville on the east side and one at Black Sage Pass on the west side.

  • The road was only open in the summer months, as the winter snow made the route impassable.
  • Apparently, the owners of the toll road did not keep good care of the road and charged what was thought to be high rates.
  • In 1887 the county purchased the road for $1,400 and took over the maintenance.

Old Monarch Pass

In 1919, work began on a new, shorter, less steep and dangerous route which is known today as “Old Monarch Pass”, elevation 11,375′.

  • This new ‘old’ route was opened to automobiles in 1921, and the older route was largely abandoned. 
  • The new route merged with the old, old road on the west side of the pass at the top of all the sharp hairpin curves, about 5 miles above the Whitepine Road, and from there the hairpin curves crisscross the old, old road.

SINGLETRACK from the Summit

The old, old road is now a dirt bike and mountain bike trail, at least in the lower stretches.
