It is a steady climb from the meadow to Lake O’Hara. The trail takes us 
along the base of Cathedral Mountain, with glimpses of Pope’s Peak and, higher 
up, the rock walls of Wiwaxy Peak, over rock slides and old moraines. The 
larger part of the trip is through woodland, but we should be constantly on the 
watch for “finds”. Lophozia Hatcheri and L. longidens occur on the earth over 
the rocks. Pleuroclada albescens is found on the stones in the small streams, and 
Scapania cor difolia on the earth beside them. On the wetter ground we should 
look for Sphenolobus politus, and, i.n the damp spots, S. scitulus and Nardia 
Breidleri. On the debris and on the stones in the streams there are small shallow 
patches of Arnellia fennica. Approaching the lake, we pass the small meadow 
that leads from it, and may find Nardia geoscyphus and Gymnomitrium varians 
growing on grassy tufts of earth. Finally we reach what seems to be a small 
lake, though it is really an arm of Lake O’Hara. The latter is but a cup surround- 
ed by mountains, some of which are among the highest and most difficult in the 
Rockies. Mount Hungabee, 11,447 feet, and Mount Deltaform, 11,225 feet, 
have the reputation of being the most difficult. Lake O’Hara is itself over 6,600 
feet above sea level, so that its flora is decidedly alpine. Lake Oesa, however, 
which empties into it over the cliffs at the southern end, is even more arctic, 
being frozen nearly the year round. 
We may camp near the arm of the lake, or press on along the trail to near 
the base of the falls from Lake Oesa. In any case, we are sure to find interesting 
plants. I have merely skimmed a part of it, but around the lake, on damp to 
wet earth, the following Lophozias occur: — LL. confertifolia, quadriloba, porphyro- 
ieuca, ventricosa, longidens , lycopodioides , Lyoni, Floerkii, heterocolpa, incisa, 
Kunzeana, and Schultzii. Wherever a stream runs, on the stones and earth, 
plants rarely met outside the highest regions may be found: — Anthelia Juratzkana , 
Sphenolobus scitulus , S. Michauxii, and S. politus , Jungermannia sphaerocarpa , 
and J. atrovirens. On a rock by the trail, near the lake, Ptilidium californicum 
and Cephaloziella Brinkmani grow associated. The feeling all along is not what 
we have found, but what we have missed. 
All around, the mountains, with their everchanging forms and vistas, invite 
us to frequent rests and contemplation. Yet the height seems to have an ex- 
hilarating effect that enhances our power of enjoyment. Our eyes are cleared, 
our lungs strengthened, our nerves steadied, and our muscles hardened: we feel 
that the trip was worth while from the point of health alone. We go to rest 
amid the smell of the firs, thoroughly tired, and waken, however early the hour, 
refreshed and eager for another day of enjoyment, with an appetite for the plain- 
est meals, possible only under some such circumstances. And the multitude of 
beautiful views impresses itself so on our memory that long afterward we enjoy 
the beauty and glory of it all, even though the feeling may be tempered with 
regret that we have visited only one of the many hundreds of beautiful valleys 
amid the Rockies.
