Whitebark pine is common but patchy in occurrence in this area with much variation in the distribution of age-classes (young, middle-aged, and dead and dying comprise most populations) and no (or at least not much in the way of) signs of disease (e.g., blister rust and animal predation of oozing bark). This site lies just north of Pinchot Pass in the the Lake Marjorie basin.

Growing in a poor fen on moist microsites on peat hummocks in full sun. About 40-50 individuals in an ~1/10 of an acre area. Most individuals in full flower, and a few with flowers starting to wither. With Dasiphora floribunda, Ledum decumbens, Festuca altaica, Equisetum fluviatile, Carex limosa, C. gynocrates, Betula nana, Myrica gale, Linnaea borealis, Picea mariana (dwarf), Trichophorum alpinum, Oxycoccus microcarpus, Platanthera dilatatum, P. huronesis, Arctous rubra, Drosera rotundifolia, and Triantha glutinosa.

Growing in a sandy-gravelly inactive alluvial/colluvial fan deposit in the alpine zone. Pinnae strongly overlapping one another and the rachis; basal pinnae spanning an arc greater than 180 degrees; inner margins of the basal pinnae strongly recurved. With Festuca altaica, Solidago multiradiata, Dryas ajanensis, Geum rossii,Botrychium ascendens, Aster sibricus, and Rhytidium rugosum.

Growing in a crevice in a calcareous rock outcrop near a calcareous seep on a steep south-facing slope. Alpine Tundra best fit given options in Vegetation type (Alaska) drop down list, but partially vegetated is actual vegetation type.

Alpine rocky ridge. Growing in rocky, dry soils, and on small ledges on a rocky outcrop. Found 4 individuals. According to "Alpine Plants of the Northwest Wyoming to Alaska" by Pojar and MacKinnon, the flowers of this plant start out pink/purple but later on in the summer they turn white.

Bog. Wet, organic soils. Very diminutive and difficult to see. Ranging in height from 3 to 10 cm. Found 3 individuals, one of which had a damaged upper part of the stem. It appeared maybe a moose had stepped on it. With Chamaedaphne calyculata, Myrica gale, Spiranthes romanzoffiana, Drosera rotundifolia, Carex rotundata, Carex pauciflora, Juncus triglumis, and Sphagnum squarrosum.

Alpine scree slope. Soils dry, and sandy-gravelly. Elevation = 5,600 ft. Several dall sheep beds in the area. With Epilobium latifolium, Saxifraga bronchialis, Trisetum spicatum, and Ranunculus grayi.

Growing on alpine summit of South Suicide Peak on metamorphic boulders. 5,007 feet elevation. Full sun, very dry. With several other Umbilicaria spp. and crustose lichens. Tick marks in photo with scale are millimeters.
