As the 70s closed, climbing styles in Tuolumne and elsewhere changed. Climbers began placing protection from hooks and rappel. Rope rests and hangs for progress came into play. Higgins wrote a critique on changing climbing styles, "Tricksters and Traditionalists" for the Sierra Club publication, "Ascent". The article was selected for a compilation, "The Best of Ascent, Twenty-five Years of Mountaineering Experience" The term traditional climbing coined in the article describes the prevailing style up to the mid 70s and now denotes a camp and philosophy of climbing – "Traditional climbing" as opposed to "Sport climbing."
