Historic Chinook Pass Entrance Arch Restoration Nears Completion

  The Chinook Pass Entrance Arch, as drawn by the staff of the Historic American Engineering Record.
Mount Rainier park craftsmen have completed the year-long restoration work on the Chinook Pass Entrance Arch, a unique historic structure in the National Park system.  Spanning across the Mather Memorial Parkway (SR 410) at 5,432 feet in elevation on the eastern boundary of the park, the arch
was designed as both an entrance portal and an equestrian overpass, to convey hikers and riders on the Pacific Crest Trail.  Built in 1936 by the Civilian Conservation Corps, the Rustic Style arch had deteriorated due to the elements and nearly eight decades of use.  The final phase will take place on Monday, August 22, when the log stringers will be put in place.

The restoration project replaced inkind all of the deteriorated parts of the structure, including replacement of the log stringers that support the bridge deck and repair of the stone masonry abutments.  Deteriorated components of the arch were removed last season, including the log stringers and masonry to prepare for replacement.  Replacement logs were shaped and fitted according to National Park Service standards over the winter, in preparation for installation this summer.

The entrance will remain open, but visitors traveling on State Route 410 are advised that short traffic delays will occur as the logs are put in place.

When the project is complete, there should be no discernible changes for visitors, except the remarkable structure will be in good condition for another 80 years of service!

Rehabilitation of 10 miles of Stevens Canyon Road Planned in 2011, 2012 and 2013

Mount Rainier National Park News Release
Mount Rainier National Park Acting Superintendent Randy King and Federal Highway Administration, Western Federal Lands Highway Division officials announce that Phase 1 of the planned rehabilitation of  Stevens Canyon Road was awarded to MidMountain Contractors, Inc. of Kirkland, WA for $2,322,367.90 with a Notice to Proceed issued for project start on Monday, August 15, 2011 and a contract completion date of October 30, 2011.

The National Park Service prepared an Environmental Assessment and a Finding of No Significant Impact (FONSI), which was approved by the Pacific West Regional Director on July 1, 2010.  The FONSI calls for the resurfacing, restoration, and rehabilitation of the Stevens Canyon Road and other related facilities, including bridges, tunnels, culverts, guard walls, retaining walls, turnouts and the short Wonderland Trail section adjacent to Reflection Lake. The improvements will occur along two segments of the road, totaling 10.09 miles of the 19 mile road.  Segment 1 begins at the Nisqually Paradise Road intersection and extends east for 4.83 miles to the Stevens Creek Bridge. Segment 4 begins at the Backbone Ridge Viaduct (just east of the Backbone Ridge Viewpoint) and continues for 5.26 miles to the intersection with Washington State Route (SR) 123.

Ten sites in Segment 1 and 35 sites in Segment 4 have been identified as needing subsurface stabilization to halt roadway embankment creep that has resulted in surface tension cracks and appreciable horizontal and vertical displacement. Two of the 10 sites in Segment 1 require full roadway embankment replacement down to 22 foot depth and retaining/guard wall replacements.  Most of the 35 sites in Segment 4 require either ¾- width or full road embankment replacement down to 5 foot depth, some of which require retaining/guard wall replacements.

Due to the scope of the extensive roadway embankment stabilization efforts, it will be necessary to close the east end (Segment 4) of Stevens Canyon Road from the gate located just west of the Grove of the Patriarchs (see attached map) to just east of the popular Backbone Ridge Viewpoint from September 6, 2011 to the end of the contract period on October 30, 2011. Pending weather conditions, the roadway will likely be shut down for the winter season upon project completion. The contractor will also be doing subsurface compaction grouting in both road segments to stabilize the roadway in 2011.  Visitors will be able to access the Reflection Lakes area, Box Canyon and Backbone Ridge Viewpoint area and adjacent trailheads from the west during the 2011closure period.


Under a separate contract yet to be advertised, Phase 2 will take place during the 2012 and 2013 seasons, which will involve subsurface stabilization work on the west end (Segment 1) and require closure from just east of the Paradise Valley Road to the Box Canyon Area immediately following Labor Day 2012 to when the road is shut down for the winter. The contractor will also be repairing the tunnel walls at milepost 6.9 and 8.5 during the closure period.  During this period, visitors will be able to access up to the Box Canyon area from the east.  From approximately June 2012 to just before Labor Day 2012 the contractor will be conducting work in both segments, at which time visitors should anticipate 20 minute delays Mondays through Fridays.

During the 2013 season, the contractor will focus on drainage improvements, repair/stabilization and reconstruction of historic rock retaining walls, milling/recycling the asphalt surface as road base; and resurfacing with new hot-mix asphalt which will be accomplished while the roadway is open to the public. At this time visitors should again anticipate 20 minute delays Mondays through Fridays until project completion estimated in September, 2013.

Stevens Canyon Road connects the east and west side of the park, extending for 19 miles from SR 123 at the east end to intersection with the Nisqually to Paradise Road at the west end, two miles south of Paradise. During the 2011 & 2012 closure periods, visitors are encouraged to access the Paradise area from the southwest via the Nisqually Entrance at east end of SR 706. Visitors traveling from the east via SR 410, SR 123, and/or US 12 who wish to visit the Paradise area have two detour options:  Via Gifford Pinchot National Forest Service Road 52 (Skate Creek Road) beginning on US 12 in Packwood and ending on SR 706 east of Ashford; or the longer route via SR 7 beginning in Morton on US 12 and ending on SR 706 at Elbe (see attached map).

While the construction and associated closures and traffic delays present an inconvenience, the rehabilitation work will not only improve the driving surface of the roadway, but ensure its longevity.

Night Sky Programs Aug 5 and Beyond!

Star Party and Night Skies Program at Paradise: 9:00 PM, Friday August 5, 2011.

Families and individuals of all ages are invited to the Paradise area of Mount Rainier National Park for a special program on Friday, August 5. The event starts at 9:00 PM in the lobby of the Paradise Inn with a short presentation about the National Park Service “Night Skies” program.  The National Park Service has come to embrace night skies as one of the many scenic vistas the agency is a steward of. It is essential to keeping a park whole and touches on almost every aspect that is important to us - from
sustainability to stargazers, and animals to ancient ruins.

At 9:45 PM there will be outdoor star gazing in front of the Paradise Jackson Visitor Center with Tacoma Astronomical Society (TAS) volunteers and their telescopes. Astronomy Society volunteers will also assist  with special children's astronomy activities.  All ages will be able to make astronomy devices called "star finders."

If weather makes star gazing difficult, the party will move inside the Paradise Inn lobby for a 45-minute film about the Milky Way galaxy.

Night Sky viewing at the park through Labor Day

Visitors are also invited to join Mount Rainier volunteer astronomer-interpreter Don West-Wilke for night sky viewing Thursdays through Sundays through Labor Day.  Don and his unique telescope will help visitors see the night sky (weather permitting) beginning at 10 PM at the following park locations:
Thursdays: Longmire Plaza in front of the National Park Inn
Fridays: Plaza in front of the Paradise Jackson Visitor Center
Saturdays: Plaza in front of the Paradise Jackson Visitor Center
Sundays: Backbone Ridge pull-out along Steven's Canyon Road
Mondays: Plaza in front of the Paradise Jackson Visitor Center

If you have questions please contact Park Ranger Curt Jacquot at (360) 569-2211, extension 6577.

Information about the Tacoma Astronomy Society is found online at: http://www.tas-online.org/
