At over 3000' of roped climbing, the North Ridge of Mt. Stuart is the longest climb I've ever done. Though most of that climbing was easy. Exum Direct on the Grand Teton was nearly as long. Epinephrine is 2200' with most of it in the 5.8 to 5.9 range.   Close behind those are the South Ridge of Salbit (1900'), Ellingwood Ledges (1900'), NE Ridge of Bugaboo Spire (1600' of climbing and 700' of scrambling, all in alpine conditions), Trap Dike (1900'), Wolf's Head (1600'), Royal Arches (1600'), Visite Obligatoire (1500'), Royal Flush (1500') and Palavar les Flots (1400').  Mt. Conness requires 2500' of climbing and scrambling to ascend nearly 1500 vertical feet, and is similar to Matthes Crest with about 2500' of climbing mostly along a ridge.  Solar Slab is 1500' if you include the approach pitches and we hit the summit at 10:18am.  At El Potrero Chico I did a bunch of tall climbs: Space Boyz, Yankee Clipper, and Time Wave Zero (to p16).  Other climbs around 1000' or more include the South Face of Washington Column, South ridge of Bergseeschijen, First Flatiron, Angel's Crest, The Grand Wall, Moonlight Buttress, Margarine Ridge, Petit Grepon, Black Orpheus, Crimson Chrysalis, Inti Watana, Fairview Dome, Full Dark Shadows, Full Dream of Wild Turkeys, NE Face of Pingora, Charlotte Dome and Snake Dike.  Crestone Needle (14,167') and Mt. Shasta (14,162') are my two fourteeners. Crestone was a technical ascent via Ellingwood ledges. Shasta was a long day of scrambling up the Avalanche Gulch route with ice axe and crampons starting at just 6880'. My lifetime high point is 15,617' which I reached while treking in the Cordillera Blanca.  Also reached approximately the same elevation trekking in Nepal.  The South Face of Washington Column and Moonlight Buttress are my two big wall (Grade V) climbs.  Black Orpheus, E Ridge of Wolf's Head, Eagle Dance, Epinephrine, Levitation 29, Inti Watana, Margarine Ridge, NE Ridge of Bugaboo, Exum Direct, Mt. Stuart, Angel's Crest, NE Face of Pingora, Rainbow Buttress, Charlotte Dome, Visite Obligatoire, and South Ridge of Salbit are the sixteen Grade IV climbs I've done.  Time Wave Zero is also Grade IV, but I only made it to pitch 16.  I've twice spent the night deliberately on the cliff -- on the South Face of Washington Column and on the top of Castleton.  One miserable, windy, cold night was spent accidentally (though not totally unexpectedly) at the top of Black Velvet after climbing Epinephrine.

I'm a pretty conservative climber (and really scared of falling) so I rarely lead trad harder than easy 5.10.  But when it comes to sport climbing I've led quite a few 5.11 climbs -- Different Strokes, Random Precision, Critters on the Cliff (onsight), Jungle Trundler (redpoint), Armed Insurrection (onsight), Captain Blondie Sinks The Ship, Hot Drama Teacher, I'll Take Sue, Johnny On Roofies, Burning Bush, Edge-A-Sketch, Buccaneer, and Johnny B. Good at Red River Gorge; Ancient Art at Fisher Towers; Levitation 29, Caustic, Drilling Miss Daisy (redpoint), Totally Clips, Under The Boardwalk, Glitter Gulch (redpoint) and Gridlock at Red Rock; Chicks in the Woods, Cynarete, G-String and Tongulation at New River Gorge; Fealine and Ivory Tower at Rifle; Monaco at Joshua Tree; Big Angler, Finland, Fucking the Dog (redpoint), Know Ethics (redpoint), and Three Easy Pieces at Rumney; Circus In The Wind, Godfather 2, and Character Witness at Ten Sleep Canyon; Super Nova (p1, onsight) and La Presa at El Potrero Chico.  My hardest Gunks leads are Criss Cross Direct, MF (first pitch direct, onsight), Never Never Land, Beatle Brow Bulge, P38 and Retribution all 5.10a and 5.10b climbs.

One more list, then I'm done.  Promise.  The final list are the climbs I've done from Gary and Lynn Clark's North American Classics.  I'm not trying to do every climb on the list, but it would be cool to climb all which are within my ability.  So far I've climbed thirty six: Ancient Art, NE Ridge of Bugaboo Spire, Castleton, Cathedral Peak, Charlotte Dome, Crimson Chrysalis, Culp-Bossier on Hallett Peak, Durrance and El Matador on Devil's Tower, Ellingwood Ledges on Crestone Needle, Exum Direct on The Grand Teton, Eagle Dance, Epinephrine, Fairview Dome, Third Flatiron, South Ridge of Mt. Gimli, The Grand Wall, East Buttress of Middle Cathedral, Moonlight Buttress, Mountaineer's Route on Elephant's Perch, Mt. Conness, NE Face of Pingora, Snake Dike on Half Dome, Lost Arrow Spire, Matthes Crest, Petit Grepon, Prince of Darkness, Royal Arches, South Face of Washington Column, Space Boyz, Mt. Stuart, The Mace, Traveler Buttress, Whitney Gilman, E Ridge of Wolf's Head, and Yellow Spur.
