Abstract

Tree rings of subfossil trees buried by lahars and lahar-derived sediments along the Sandy and Zigzag Rivers record the onset of a late eighteenth century eruption at Mount Hood, Oregon, USA (Figs. 1–2). Crandell (1980) described and named this eruptive activity the ‘Old Maid eruptive period’ and estimated its age at about “200–300 year” using radiocarbon ages of trees killed by lahars. Cameron and Pringle (1986, 1987, 1991) used dendrochronology to constrain the major eruptive events to several decades in the late 1700s. Precise dating of the Old Maid eruption using tree rings, however, has been complicated by the inconsistent wood quality and scarcity of victim subfossil trees. A lack of nearby master chronologies, diverse physiography and microclimates of the region, and the generally low sensitreivity of local tree-ring series to climate variation also create problems with interpretation.

Notes

Acknowledgments

In 1997, Blythe Underwood Creek, an amateur geologist, found additional buried trees, including a key bark-bearing western redcedar snag, and assisted us in sampling these.
