Boundary changed The boundary of the Grand Canyon National [Park](/usc/16/410r–5.md?p=c-3) is changed so as to read as follows: Beginning at a point on the present south boundary of Grand Canyon National [Park](/usc/16/410r–5.md?p=c-3), being the northeast corner of township 30 north, range 1 east, of the Gila and Salt River meridian, Arizona; thence westerly along north line of said township to the northwest corner of [section 1](/usc/16/1.md), said township; thence northerly along west line of [section 36](/usc/16/36.md), township 31 north, range 1 east, to a point one-half mile south of the center line of the Supai road survey as mapped and staked by the Bureau of Public Roads during the field season of 1925; thence in a northwesterly direction following a line, which maintains a uniform distance one-half mile south and west of the center line of said road survey, to its intersection with the projected section line between what probably will be when surveyed sections [9](/usc/16/9.md) and [16](/usc/16/16.md), township 32 north, range 2 west; thence westerly along projected section lines through probable townships 32 north, ranges 2, 3, and 4 west, to its intersection with the upper west rim of Havasu (Cataract) Canyon; thence northwesterly along said upper west rim, crossing Hualapai Canyon to Wescogame Point and continuing northwesterly along said upper rim to Watahomigie Point; thence due north along the top of a ridge a distance of approximately three-fourths of a mile to the point of said ridge, the elevation of which is given as four thousand eight hundred and sixty-five feet; thence northwesterly, crossing Beaver Canyon, to Yumtheska Point and continuing northwesterly, following the lower rim of Yumtheska Point, crossing the projected range line between ranges 4 and 5 west to the divide west of Havasu Creek; thence northerly along said divide to the north bank of the Colorado River; thence northeasterly along said bank to the divide immediately west of Tapeats Creek; thence northeasterly along said divide, including the entire drainage [area](/usc/16/539m–1.md?p=1-A) on the north side of Tapeats Creek, to the point at which this divide touches the ledge of cross-bedded sandstone; generally known as the Coconino sandstone; thence southerly along said sandstone ledge to its junction with the Gila and Salt River meridian; thence southerly along the Gila and Salt River meridian to the northwest corner of what will probably be when surveyed [section 18](/usc/16/18.md), township 34 north, range 1 east; thence easterly along projected section lines to the northeast corner of what will probably be when surveyed [section 14](/usc/16/14.md), township 34 north, range 2 east; thence southerly along projected section line to the southeast corner of said [section 14](/usc/16/14.md); thence easterly along projected section lines, a distance of approximately six miles to a point on the divide between South Canyon and Thompson Canyon; thence southeasterly along said divide, including the entire drainage [area](/usc/16/539m–1.md?p=1-A) of Thompson Canyon and Neal Spring Canyon, to the intersection with the upper rim of the Grand Canyon; thence easterly along the main hydrographic divide north of Nankoweap Creek and Little Nankoweap Canyon to its intersection with the Colorado River, approximately at the mouth of Little Nankoweap Canyon; thence due east across the Colorado River to the east bank of the Colorado River; thence southeasterly along said bank, to the north bank of Little Colorado River; thence easterly along said bank of Little Colorado River to its intersection with what probably will be when surveyed the east line of [section 32](/usc/16/32.md), township 33 north, range 6 east, or the east line of [section 5](/usc/16/5.md), township 32 north, range 6 east; thence southerly along projected section lines to the northeast corner of what probably will be when surveyed [section 8](/usc/16/8.md), township 30 north, range 6 east; thence westerly along projected section lines to the southwest corner of what probably will be when surveyed [section 6](/usc/16/6.md), township 30 north, range 5 east; thence southerly to the northeast corner of [section 13](/usc/16/13.md), township 30 north, range 4 east; thence westerly to the northwest corner of said [section 13](/usc/16/13.md); thence southerly to the southwest corner of said [section 13](/usc/16/13.md); thence westerly along section lines to a point nine hundred and fifty feet west of the northeast corner of [section 22](/usc/16/22.md), said township; thence due south a distance of one thousand three hundred and twenty feet to a point on the south line of the north tier of forties of said [section 22](/usc/16/22.md); thence westerly to the west line of said [section 22](/usc/16/22.md); thence southerly along said west line, to the southwest corner of said [section 22](/usc/16/22.md); thence westerly along section lines to the southwest corner of section 19, township 30 north, range 4 east; thence northerly to the northwest corner of said section 19; thence westerly to the southwest corner of [section 14](/usc/16/14.md), township 30 north, range 3 east; thence northerly to the northwest corner of said [section 14](/usc/16/14.md); thence westerly on section lines to the southwest corner of [section 12](/usc/16/12.md), township 30 north, range 2 east; thence northerly along section lines to the north line of said township 30 north, range 2 east, thence westerly along said north township line to the place of beginning; and all of those lands lying within the boundary line above described are included in and made a part of the Grand Canyon National [Park](/usc/16/410r–5.md?p=c-3); and all of those lands excluded from the present Grand Canyon National [Park](/usc/16/410r–5.md?p=c-3) are included in and made a part of the contiguous national forests, subject to all national forest laws and regulations. ## Source credit (Feb. 25, 1927, ch. 197, § 1, 44 Stat. 1238.)
