The book by Parker apparently is becoming known as the telemarkers
bible. It is easy to see why.
Free-heel Skiing, 2nd Ed.
The Mountaineers, 1995
ISBN 0-89886-412-7 paperback 190 pp.
The next book actually says nothing at all about telemarking or free
heel skiing in any form. However, skiing is skiing and this is a
superb book. With this and Parkers book, you would have all the ski
technique books you would ever need. Also, as virtually every good
telemark book tells you, you should learn how to do parallel turns on
your tele gear (hint: rent or borrow alpine gear and buy a lift ticket.)
Breakthrough on Skis
Vintage Books (Random House), 1986
ISBN 0-394-74703-8 paperback 291 pp.
The next one has chapters on nordic touring, telemarking, AT gear, and general
backcountry business in the snow. Even some sobering pages on extreme skiing.
It is amazing how little has changed in almost 20 years.
Also amazing what a well-rounded skier Lito Tejada-Flores is.
