To settle the question of whether the Santa Lucia Range holds the title, geomorphologists look to Cone Peak. Located in the Ventana Wilderness approximately 3 miles inland from the Big Sur shoreline, Cone Peak reaches a surveyed elevation of 5,155 feet (1,571 m) above sea level.
Measuring the gradient "as the crow flies" from the peak's summit southwest to the Pacific surf reveals a horizontal distance of roughly 17,000 feet (about 3.25 miles or 5.2 kilometers). That produces an average gradient of approximately 30% (around 1,580 feet per mile). To put that in perspective, a standard highway grade rarely exceeds 6% or 7% without runaway truck ramps. Cone Peak climbs at more than four times that angle, starting from the waterline itself.
Other contenders in the Pacific Northwest boast higher coastal peaks, but they fail the distance test. Mount Olympus in Washington reaches 7,980 feet, but its summit sits roughly 33 miles (53 km) inland. Mount Rainier towers over Puget Sound at 14,411 feet, yet its base rests dozens of miles from saltwater. Closer rivals such as King Peak in Northern California's Lost Coast mount a formidable challenge, but Cone Peak edges them out on pure, unbroken gradient from sea level.
