PEALEl LOWER GEYSER BASIN WHITE DOME GROUP. 165 



IsTo. 7 marks the location of a cluster of springs and steam vents near 

 the creek on the north side, not far below No. 5. No. 8 is at the upper 

 end of the cluster, in which there is a violent bulger (8 e), which has a 

 triangular opening in laminated deposit. Its temperature is 199° F. 

 On the opposite side of the creek (opposite Nos. 7 and 8) there are several 

 springs not included in the table. 



Springs Nos. 9-18 form a cluster, all but one of which is on the same 

 side of the creek as No. 8, but farther south. They are principally located 

 on a mound of deposit. 



No. 9. This is a diamond-shaped pool 18 feet long and 8 feet wide, in 

 which the water has a green tint, which contrasts well with the white 

 basin in which it is contained. It is near the base of the mound, rather 

 close to the creek, and has a temperature of 178° F. 



No. 10 is on the summit of the mound, and is a very handsome cavern- 

 like spring, with a white yellow-lined border surrounding greenish- 

 tinted water. It is irregular in shape, measuring 20 by 30 feet in its 

 greatest dimensions. One end of the spring has a hammer-head shaped 

 prolongation, in which there is a black center of ebullition, where the 

 temperature is 199° F., while in the pool it is only 182° F. Back of 

 this spring is a ravine from which there flows a stream of pure, cold, 

 drinkable water, which is an interesting fact to the visitor of this group, 

 as in most parts of the basin he is in much the condition of Coleridge's 

 mariner, surrounded with water, but "not a drop to drink." 



Crossing this cold stream or rivulet we find the remaining springs of 

 the cluster. 



No. 11 is a nearly circular (9 feet diameter) gray-lined spring, with a 

 white edge, in which the water has a bluish tint. The outlet is yellow 

 lined. The water has a temperature of 181° F. 



No. 12 is a spring of low temperature (140° F.), and, as is usual in 

 such springs, it is lined with a leathery-looking substance (probably a 

 variety of viandite) of red and greenish-brown colors. 



No. 13 is a yellow and white lined basin, with rounded triangular sides, 

 measuring, respectively, 4 feet, 5 feet, and 6 feet. 



Nos. 14-17 are sufficiently described in the table. 



No. 18 is on the opposite side of the creek, on the edge, and opens 

 directly into it. 



The next cluster (19-23) is on the west or southwest side of the creek, 

 farther up, and are raised but little above its level. 



No. 19 is a beautiful greenisli spring, 15 feet in diameter, with a white 

 border and a temperature of 182° F. It is back from the creek, next the 

 edge of the timber. 



No. 20 is a bulging hole back of No. 21, with which it is connected. 

 The water is thrown up in a splashing mass, and has a temperature of 

 199° F., whereas in No. 21 the temperature is only 103° F. 



A short distance above this cluster, on the same side of the creek, is 

 another (Nos. 24 to 29). 



Nos. 25 and 26 are long and narrow, and appear to be openings into a 

 subterranean outlet from No. 24. There are several holes in the cluster 

 that are not included in the table. 



Some distance above this cluster, on the opposite (east) side of the 

 creelc, at the upper end of a small meadow, are three small basins, the 

 principal one of which (No. 30) is a bulger and has a temperature of 

 189° F. 



Crossing the creek again, we find on the west side a cluster (Nos. 31, 

 32) almost opposite No. 30. The principal spring (No. 31) is a largo
