In the opposite direction, good trails lead to the Illecillewaet Glacier, and to Asulkan Pass and the Asulkan Glacier, from which it is possible to reach a group of magnificent peaks, Castor and Pollux, The Dome, Clarke, Swanzy, and a little farther to the west Bonney and Smart. On the opposite side lies the vast Illecillewaet snow-field. From Glacier House, again, a good carriage road takes you west parallel with the railway and the Illecillewaet River, towards Cougar Mountain and Ross Peak. Eventually this will be extended to the Nakimu Caves. At present a trail follows the same route to the Caves, and around Mount Cheops to Rogers Pass, thus providing a round trip, from Glacier House to the Caves, thence to Rogers Pass, and back to Glacier House again. The Nakimu Caves were discovered accidentally some nine years ago, and are said to be well worth visiting. They are in charge of C. H. Deutschmann, who discovered and explored them, and thanks to his competent guidance and the facilities that have been provided it is now possible for any one to visit and examine this curious freak of nature. It will be more convenient to describe the Caves in another chapter. Those who would really wish to know the character, extent and variety of the scenery in Glacier Park and the great mountain range of which it is only a small part, are recommended to consult A. O. Wheeler's delightful guide-book, _The Selkirk Mountains_, and the same author's exhaustive work published by the Dominion Government, _The Selkirk Range_. These are not only readable and authoritative, but with the exception of Green's _Among the Selkirk Glaciers_, they are the only books available on this very important region.[3] [3] Since the above was written Howard Palmer's _Mountaineering and Exploration in the Selkirks_ has been published, making a very important addition to the scanty literature on the subject.
