is not uufreqiient in the Rocky Mountains, and that their frequency and 

 the extent of damage occasioned by them must be exi)ected to increase 

 as popuhition and development there progress. 



NoTK. — Mr. William N. Byers, C. E., a close observer aucl long resident of Colorado, 

 says: The main dilterence existing between onr monntaius and those of the Old 

 World lies in the fact that there glaciers abound while we are free from them. The 

 great extent of platean country causes the high temperature of the mountain ranges, 

 and is the canse of the snow melting off yearly, in direct contrast to the mountains 

 of Switzerland, thus causing a higher snow-line with us. 



" Snow-slides are very common in Colorado, and most common in the San Juan near 

 the main range. They occur every year, and, when snow falls to any extent, fre- 

 quently, and many lives are lost." (Last year two hundred lives ar^ reported to have 

 been lost.) 



March is said to be the most dangerous month in the San Juan, and, as an old 

 miner expresses himself, "It is hard to say as to where it is safe to live in San Juan.''' 



Commissioner of the Land Office, Williamson, in his report for 188."), states : "It may 

 be noted also as another incident to this total destruction of timber along the can- 

 yons, that 'snow-slides' are of frequent occurrence in the denuded localities of the 

 mining settlements, and that during the past winter some were attended with serious 

 loss of life and property. 



To show the not infrequent occurrence and disastrous effects of snow-slides and 

 land-slides, the following newspaper clippings, taken within the last few years, have 

 been here in part reprinted : 



The well-known disaster at the Emma mine, a few years ago, will probably be re- 

 membered by all in Utah. 



Helena. Mont., Mau 7, 18-'5.— The land-slide 1 mile east of Thompson's Falls, May 

 4, is not yet cleared. Water oozes from the ground 1,000 feet above the track. It is 

 feared that the entire mountain side will be precipitated. 



Silverton, Colo., Decemlcr 22, 1885. — The first snow-slide of the winter occurred to- 

 day, coming down the mountain into Minnesota Gulch. The slide struck the mouth 

 of the Prodigal Son mine, filling the 85-foot shaft and burying two men who were 

 working at the bottom. The snow was packed so tightly that it was found to be im- 

 T)ossible to move the bucket. The news of the accident Avas a great surprise, as it was 

 not supposed sufiflcient snow had fallen on the mountain to make a slide that would 

 cause damage.
