Show Scientists Blame River for fOl- Land Sink in Idaho Disturbance What Geologists Geologists Call Calla a Landslip On Washington the basis ot of re- re reports reports ports and photographs received re- re recently recently from its field office in Idaho the geological survey Department ot of the Interior announces that the theland theland land disturbance near the Salmon Falls FalIs river in the vicinity of Buhl is a landslide of the gradual modi- modi modified fled fied type known to geologists as a landslip The The- reports refute the the ory that a sink had developed in the region The performance Is neither super super- supernatural supernatural natural nor mystical nor is it with with- without out precedent the geologists de de- deClare clare Land will continue to 10 settle by either the landslide or sink ENVOY TO ERIN v t tk k Y U K 41 f 7 f- f H 1 I f f i w i f p m John Cudahy newly appointed minister to the Irish Free State Slate IS shown as he sailed aboard the liner Manhattan to take up his ministerial duties Until recently he was the minister to Poland methods until the of the earth are definitely located set setin setin in place and established maybe years from now maybe even geologists are un un- un uncertain certain Rivers ers Pc Performance Explained E Idaho's performance is explained in detail The Salmon Falls river southern tributary of the Snake riv river er has cut a rather steep walled canon canyon into the beds of the Snake river plains The river un- un undercuts un the canyon walls walIs from time timeto timeto to time and large masses of earth break away some of them settling in the bottom of the canyon and others on the sides The blocks that break off are of various sizes and as they begin to break cracks appear at the landward edges In Inthe I Ithe the case of at large blocks these cracks may sometimes be several hundred feet from the edge of the canyon This appears to be the I case In the phenomena at Buhl Sometimes a great block may slide suddenly in one avalanche to its final resting place more Ire fre it moves a little at a time settling gradually into its new position position tion Movements of this kind may result directly from undercutting of the base of cliffs by streams or from irrigation which soaks the soil Citing other land demonstrations demonstrations- within the memory ot of this genera lion tion the geologists recall an occur occur- occurrence occurrence rence near Sharon Springs Kan on March 9 1926 when l a tract ot of good farm land feet feel long and feet wide suddenly collapsed and sank to toa toa a depth estimated by early visitors to be feet or more The cause was assigned to a cavern developed III the underlying chalk beds Some years earlier August 10 to 12 1910 R a series of three sinks developed in the streets on the out skirts ot of Staunton Va One small frame house was engulfed a neigh neigh- neighboring boring brick house was partly destroyed de- de destroyed and a fIre engine house was partly undermined This as well as the Kansas catastrophe was attrib- attrib attributed attributed to sinks Also the landslide has produced some memorable and outstanding disasters the repeated slides duro dur- during ing construction and early opera opera- operations operations of the Panama canal being most familiar In that instance the Culebra cut was bordered by rocks of volcanic derivation rendered un un- un unstable stable by frequent wettin wetting and by bythe bythe the steep sides ot of the cut Similar slides occurred In the valley val val- valley ley of the Gros Ventre river 35 miles south of Yellowstone Nation al park on June 23 1925 1025 Heavy rains and melting snows in the mountains had saturated clay lay lay- layers ers and a mass ot of rock estimated at cubic yards slid sud denly down doom the valley with such force that it piled up feet against the cliffs on the opposite side and partly slumped back again The slide dammed the river and pro produced produced a lake several miles long The dam partly gave way in May 1927 and caused a flood which swept down Snake river carrying away bridges and causing loss of at six or seven lives This disaster occurred in the Snake river plain the same regIOn as 35 the present Idaho disturb ance |
