peaks, severallynamed, Lassens, Crater, Magees, and Burneys peak, separated fromeach other by spaces of ten or twelve miles. They are all of volcanicorigin, as are many other peaks and buttcs in the vicinity, and else-where in the county. Lassens Peak has four distinct summits, the highest of which hasan altitude of ten thousand five hundred and seventy-seven feet, asdetermined by Messrs. Brewer and King, of the State Geological Sur-vey, who ascended it in 1863, and ascertained its height by carefulmeasurement. These summits, rising from two hundred and fifty tothree hundred and fifty feet above the common level of the mountain,are only the remaining portions of what was once the rim of the greatt-rater, formed when this was an active volcano. Near the toj^ of thismountain occur, as in the case of Mount Shasta, evidences of long con-tinued solfatara action, which here has ceased many years since.Viewed from the north or south, this peak presents the shape pf a flat- > CDCD CD M>

It is timbered for about two thirds of the distanceto its summit, which is covered with snow on its northern slopes a goodportion of the year. Some of the cones to the north, both those alongthe line of the Sierra and others scattered over the volcanic tabic landsin this part of the county, present, in their outlines, stecj), pointedridges, while, in other cases, they have circular craters on the top, allindicating for them a common origin. They vary in height from sixthousand to nine thousand feet, there being at a point five miles northof Lassens Peak a cluster of irregular truncated cones of less altitude,and evidently of more recent formation, and Avliich, between 1854 and1857, were constantly emitting large quantities of steam and gases.Numerous traces of well marked glacial action are found on LassensPeak, at an elevation of between six thousand and nine thousand
