Editing Lemhi County, Idaho (section)

===County-boundary history===
At the start of mining operations in present-day Lemhi County in 1862, the region was fully within Idaho County, [[Washington Territory]]. [[Boise County, Idaho|Boise County]] was created in 1863, with its northern boundary running just north of the ridge dividing [[Birch Creek (Lemhi County, Idaho)|Birch Creek)]] from the Lemhi River. Under [[Idaho Territory]], the southern portion became part of [[Alturas County, Idaho|Alturas County]] on February 2, 1864, and the dividing line between Alturas and Idaho Counties was adjusted to 44°&nbsp;30′ North latitude. The Idaho territorial legislature actually created Lemhi County twice. The first occasion was on December 21, 1866. A county government was organized at Salmon City, yet the bill approving the county was misplaced and never published in session laws. The following session, the legislature passed the bill again, officially creating Lemhi County on January 9, 1869. The county government was reorganized at Salmon City on February 22, 1870.<ref>{{cite web|title=Idaho State Historical Society Reference Series: Early Lemhi County|url=https://history.idaho.gov/sites/default/files/uploads/reference-series/0329.pdf |archive-url=https://web.archive.org/web/20120503190135/http://www.history.idaho.gov/sites/default/files/uploads/reference-series/0329.pdf |archive-date=May 3, 2012 |url-status=live|publisher=Idaho State Historical Society Reference Series|access-date=February 25, 2017}}</ref> The western and southern county boundaries for Lemhi were problematic and adjusted frequently. At its creation, Lemhi inherited Idaho County's southern and eastern boundaries, which effectively created two areas of noncontiguous territory, with one of the sections containing territory along the Salt Lake to [[Virginia City, Montana|Virginia City]] stagecoach route just north of the present town of [[Humphrey, Idaho]]. Finalization of the southern boundary came in several steps from 1885 to 1896. In 1885, the boundary was moved southward, gaining territory in present [[Clark County, Idaho|Clark County]], creating a contiguous boundary, and leaving a {{convert|6|by|25.5|mi|km|adj=on}} stretch of the Birch Creek Area in Alturas County. The eastern {{convert|6|by|9|mi|km|adj=on}} portion of that territory was transferred from Alturas to Bingham in 1889. A change in 1891 extended the boundary south to its present location and added territory presently in Clark County. With legislative approval, voters in that territory voted to become part of [[Fremont County, Idaho|Fremont County]] in 1896, finalizing the southern and eastern boundary. At Lemhi's creation, the western boundary was a line drawn from the Bitterroot Mountains to the southern line of Idaho County. The boundary was moved westward to the divide between the [[Payette River|Payette]] and Salmon Rivers in 1873, moved eastward to a line drawn through the confluence of the Middle Fork and main Salmon rivers in 1885, and then mistakenly extended to the northern line of Idaho County in 1903 before being finalized at its present location in 1911. [[Custer County, Idaho|Custer County]] was partitioned from Lemhi in 1881 with its initial boundary excluding the [[Loon Creek]] area. The Loon Creek area was transferred back to Idaho County in 1885.<ref>{{cite book|title=Idaho Atlas of Historical County Boundaries|date=2010|publisher=The Newberry Library|location=Chicago|pages=12, 42, 76, 95, 98, 123–131}}</ref>
