    1. Introduction. Energy emitted by the sun runs the climate system. Low-frequency climate modulation at time-scales of 10 4 –10 5 years can be attributed to the orbital theory compiled by M. Milankovitch, but at shorter time-scales to solar variation (e.g. Eddy, ; Chambers et al., ; van Geel et al., ; Beer et al., ).The activity of the sun is not a constant, but it alternates Cited by:   In North America, few high-resolution, well dated records from lake sediments have concentrated on climate dynamics during the last six millennia. However, Elk Lake, a varved lake in Minnesota located on the prairie/forest boundary, has been extensively studied at century scale for the Holocene record and at subdecadal scale for the last 1, Cited by:

Elk Lake, Minnesota Setting. Elk Lake is a dimictic lake with a seasonally anoxic hypolimnion. Temperatures in the epilimnion and littoral-zone respond to seasonal air temperatures, commonly reaching >20°C during the summer (Megard et al., ).The lake water is derived mainly from precipitation and ground-water flow, with little input from surface-water by:

In order to build up the history of the regional climate pattern in the Altai Mts. and understand its causative factors, we certainly need to obtain more high-resolution climate records.

Lake Garba Guracha was first described by Werdecker () and Löffler ().It is a small, roughly rectangular (∼ m long, ∼ m wide) NNE-oriented lake lying in a typical glacial cirque at the end of a side valley of the upper Togona valley (Fig.
