Mount Mendel, while a worthy objective by any route, is primarily known for having two of the hardest ice climbs in the High Sierra on its North Face. The left hand gully is known as Ice Nine ( IV,5.7, WI 3-4 ) and features 1000' + of climbing including ice up to 75 degrees. The classic right hand Mendel Couloir ( III, 5.6, AI2 or WI3 ) features 1000' + of ice climbing to 60 + degrees. The right couloir is a " 100 Classics " must do route for the High Sierra ice climber.

Other routes include -

The Southwest Face - class 3 from Evolution Lake.
The Central Chute - class 4 from the lower end of Evolution Lake.
The Northeast Ridge - class 4 ( current opinion of those SP members who have actually climbed it ).
The East Face - class 3 ( lots of loose rock ).

See one of the climbers guides under books for more detailed information.

Getting There

The usual trail is the Lamarck Col cross country trail. From the North Lake trail head, follow the Lamarck Lakes trail to where it crosses the stream between Lower and Upper Lamarck Lakes. Head southwest and follow the faint trail to Lamack Col ( 12,960' ). More detailed hiking info can be found in the R. J. Secor guide. The North Lake Pack Station is also available to haul packs to near the top of Lamarck Col ( 760 - 873 - 4785 ).
The maps needed are the Mt. Darwin and Mt. Thompson 7.5 minute USGS maps.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
