Question: Which State's fish was discovered at the base of Colter Falls?
Context: Colter Falls, also Coulter Falls, (4.3m) waterfall, nearly 0.5 mi in width, part of the Great Falls of the Missouri, on the Missouri River in north-central Montana.  Downstream of Colter Falls lies Rainbow Falls, and upstream is Black Eagle Falls.  The Lewis and Clark Expedition was known to discover Westslope cutthroat trout at the base of the falls.  The falls is now flooded in the impoundment behind Rainbow Dam.  As Rainbow Dam's reservoir is a run-of-the-river reservoir, it rarely is emptied, so the falls is rarely seen even in extreme drought.  The falls was named by Paris Gibson, founder of the city of Great Falls, Montana, while they were not named by Lewis and Clark, who measured it at "6 feet 7 inches". The Colter Bay Lakeside Trail is a 2 mi roundtrip hiking trail in Grand Teton National Park in the U.S. state of Wyoming.  From the Colter Bay Marina trailhead, two short loop hikes from Colter Bay Village are connected by a causeway.  The trail follows the shoreline of Jackson Lake with the Teton Range off to the west across the lake. Colter's Hell is an area of fumaroles and hot springs on the Shoshone River near Cody in the U.S. state of Wyoming.  The thermal area covers about a square mile at the mouth of the Shoshone's canyon.  Its thermal activity has declined ever since its description by mountain man John Colter, who parted from the Lewis & Clark Expedition prior to its conclusion and passed through the region in the winter of 1807-1808.  Colter's account of the features on what was then called the Stinkingwater River has subsequently been confused with the much more extensive and powerful geysers in Yellowstone National Park, which Colter may not have actually visited. The westslope cutthroat trout ("Oncorhynchus clarki lewisi"), also known as the black-spotted trout, common cutthroat trout and red-throated trout is a subspecies of the cutthroat trout ("Oncorhynchus clarki") and is a freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes.  The cutthroat is the Montana state fish.  This subspecies is a "species of concern" in its Montana and British Columbia ranges and is considered "threatened" in its native range in Alberta. Hopi House is located on the South Rim of the Grand Canyon, within Grand Canyon National Park in the U.S. state of Arizona.  Built in 1904 as concessioner facilities at the South Rim were being developed, it is the first of eight projects at the Grand Canyon that were designed by architect Mary Colter, along with Bright Angel Lodge, Hermit's Rest, Lookout Studio, Phantom Ranch, Desert View Watchtower, Colter Hall and Victor Hall, (the latter two being employee dormitories).  Hopi House was built by the Fred Harvey Company as a market for Native American crafts, made by artisans on the site.  The Hopi, as the historic inhabitants of the area, were chosen as the featured artisans, and the building was designed to closely resemble a traditional Hopi pueblo.  Hopi House opened on January 1, 1905, two weeks before the El Tovar Hotel, located just to the west, was opened. Rainbow Falls (originally "Handsome Falls") is a waterfall on the Missouri River in Great Falls, Montana, just upstream from Crooked Falls and downstream from Colter Falls and Rainbow Dam.  It is 47 feet (14m) high and 1,320 feet (402.3m) wide.  The waterfall is part of the five Great Falls of the Missouri.  The river spills over a sheer ledge of sandstone in the Kootenai Formation, forming the falls.  The falls used to flow with a great deal of force year-round.  In 1914 the river shortly upstream was dammed for hydroelectric power by the Rainbow Dam, which forms a run-of-the-river reservoir.  As a result, the falls can almost totally dry up in the summer with only a few narrow strips of water trickling down its face.  A railroad bridge crosses the river directly above the falls. Labeo bata is fish in genus Labeo.  It is commonly known as bata, and is a native fish to India and Bangladesh.  It is a popular game fish and is popular for its taste.  It lives in ponds, rivers, etc.  Its maximum length is 25 - .  It eats protozoa, algae, and tiny fishes.  It is a slow-moving fish, so with any active and aggressive it will be nervous.  The age and growth of Labeo bata (Ham.)  was studied by the analysis of annuli found on the scale and by length-frequency distribution.  The fish attained lengths of 131, 194, 236, 277, 314, 341 and 364 mm at the end of the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th years of life respectively.  The increase in length of scale bears a constant relationship with the increase in length of fish.  The growth rate of the fish was found high during the 1st and 2nd years, and decreased gradually afterwards till the 7th year.  Both sexes showed more or less similar growth rate.  The seasonal growth curve was chiefly influenced by feeding intensity in fishes of 1st year class, while in adults it was affected by feeding intensity as well as by maturation of the gonads.  The body is elongate.  Its dorsal profile is more convex than the ventral.  The snout slightly projects beyond the mouth, often studded with pores (Talwar and Jhingran, 1991).  A pair of small maxillary barbells is hidden inside the labial fold.  There is no cartilaginous support to the lips.  The dorsal originates midway between the snout tip and the anterior base of anal.  Pelvics originate slightly nearer to the snout tip than to the caudal base (Rahman, 1989).  It is bluish or darkish on upper half, silvery below, and the opercle is light orange.  Its food comprises crustaceans and an insect larva in early stages.  This fish is found throughout India(West Bengal,Odisha,Tripura etc.)and Bangladesh .  Ponds, rivers, rivulets are its main habitats (Bhuiyan, 1964).  It is listed as a threatened species by IUCN Bangladesh (2000). Colter Canyon is located in Grand Teton National Park, in the U. S. state of Wyoming.  The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago, leaving behind a U-shaped valley.  Colter Canyon is north of Ranger Peak and the entrance to the canyon is along the northwestern shore of Jackson Lake. Fish Creek Falls is a waterfall located about 5 miles to the east of Steamboat Springs, Colorado in Routt National Forest.  Fish Creek runs from several small lakes in the Rabbit Ears Range of Colorado.  In the summertime, the road to Fish Creek Falls becomes often clogged in mid-afternoon with tourists wanting to see the 283 ft waterfall.  It is possible to hike all the way to the terminus of the waterfall through giant boulders and rushing water.  There are two hiking trails from the parking lot at the end of Fish Creek Fall Road.  One is 1/4 of a mile (1/4 mi ) and goes through several Aspen groves with the occasional Subalpine Fir.  It ends at a viewing station where the entirety of the falls can be seen.  The other trail goes straight down into the U-Shaped valley formed by glaciers.  As it nears the bottom of the valley, one can hear the rushing sound of water over the fall and see beautiful Fish Creek.  The trail continues on to Upper Fish Creek Falls and then on to the Wyoming Trail, a long trail running the northwestern mountains of Colorado to Wyoming.  The falls provide a great place for ice climbing in the winter when 300+ inches of snow (300 in ) fall on the mountains east of Steamboat Springs. Fred Colter was an Arizona rancher and farmer, as well as being the State Senator for Apache County beginning with Arizona's second state legislature in 1915.  Colter spent six terms in the Arizona Senate.  He also led the fight on Arizona's behalf to maintain control over the water from the Colorado River, coining the slogan, "Save the Colorado for Arizona".  He was a close ally of the state's first Governor, George W. P. Hunt.  Prior to his election to the State Senate, Colter had served as the state's fair commissioner.
