Question: What  is the name of  the area also known as the Ridge Valley Province where a ridgeline cut through on its East side??

Context paragraphs:
Hatterrall Ridge: The Hatterrall Ridge (sometimes spelled Hatterall) is a ridge in the Black Mountains forming the border between Powys and Monmouthshire in Wales and Herefordshire in England.  The ridge is about 10 mi long, and is followed by the Offa's Dyke Path.  On the west side of the ridge is the Vale of Ewyas, and on the east side is the Olchon Valley and Black Hill.  The western side of the ridge falls within the Brecon Beacons National Park.  Much of the northern part of the ridge is a broad whaleback, but it narrows down considerably further south, and especially near to Llanthony Priory in the Vale of Ewyas to the west of the mountain.  There is a large and prominent landslip on the eastern side of the mountain here, known as Black Darren, where a large slice of the rocks has fallen away from the main mass of the hill.

Misery Mountain (Taconic Mountains): Misery Mountain, 2671 ft , with at least ten well-defined summits, is a prominent 6 mi long rideline in the Taconic Mountains of western Massachusetts and adjacent New York.  The west side of the mountain is located in New York; the east side and high point lie within Massachusetts.  The summit ridge is part meadow and part wooded with red spruce, balsam fir, and northern hardwood tree species.  It is notable for its views of the Hudson River Valley to the west.  The 35 mi Taconic Crest Trail traverses the crest of the ridgeline, but does not cross the summit.

Shenandoah Valley: The Shenandoah Valley is a geographic valley and cultural region of western Virginia and the Eastern Panhandle of West Virginia in the United States.  The valley is bounded to the east by the Blue Ridge Mountains, to the west by the eastern front of the Ridge-and-Valley Appalachians (excluding Massanutten Mountain), to the north by the Potomac River and to the south by the James River.  The cultural region covers a larger area that includes all of the valley plus the Virginia highlands to the west, and the Roanoke Valley to the south.  It is physiographically located within the Ridge and Valley province and is a portion of the Great Appalachian Valley.

Volujak (mountain): Volujak is a mountain range on the border of Bosnia and Herzegovina and Montenegro, within the entity of the Republika Srpska.  Geologically, Volujak is a subrange of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone and dolomite.  It basically forms a long ridge on the southwest side of the Suhja valley, with the border between Bosnia-Herzegovina and Montenegro running alongside this ridge, where a sharp corner of BiH territory reaches into Montenegro.  It is on the BiH side located within the Sutjeska National Park but has a protected status also on the Montegrin side.  Notable peaks are Volujak (2337 m ), Studenac (2296 m ), Badnjine (2245 m ) and Trnovački Durmitor (2232 m ).  Right at the northern foot of this last peak is the beautiful Trnovačko Lake situated.  The Volujak range borders north-east on the Suhja valley and Maglić, on the south west side on the Izgori valley and the Lebršnik mountain group, in the north west by the Sutjeska (river) valley and on the south east side by the Bioč range.  Volujak peak is the second highest elevation point in Bosnia Herzegovina.  From its summit hikers obtain an impressive view of the surrounding peaks: Maglić, Veliko Vitao and, in the distance, Durmitor.

Ridge-and-Valley Appalachians: The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian division and are also a belt within the Appalachian Mountains extending from southeastern New York through northwestern New Jersey, westward into Pennsylvania and southward into Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia and Alabama.  They form a broad arc between the Blue Ridge Mountains and the Appalachian Plateau physiographic province (the Allegheny and Cumberland Plateaus).  They are characterized by long, even ridges, with long, continuous valleys in between.

Mount Nittany: Mount Nittany is the common name for Nittany Mountain, a prominent geographic feature in Centre County, Pennsylvania, USA.  The mountain is part of a ridge that separates Nittany Valley from Penns Valley, with the enclosed Sugar Valley between them.  On USGS topographic maps, Nittany Mountain is generally shown as the lower ridge line that runs below Big Mountain on the west and Big Kettle Mountain on the east side, coming together to form a single ridge line at the southern terminus.  This nomenclature is not always consistently applied to the same geologic formation, and there is a shorter Nittany Mountain ridge shown above the Sugar Valley as well.

Kittatinny Mountain: Kittatinny Mountain (Lenape: Kitahtëne) is a long ridge traversing across northwestern New Jersey running in a northeast-southwest axis, a continuation across the Delaware Water Gap of Pennsylvania's Blue Mountain Ridge (also known as Kittatinny Ridge).  It is the first major ridge in the far northeastern extension of the Ridge and Valley province of the Appalachian Mountains, and reaches its highest elevation (the state's highest), 1,803 feet, at High Point in Montague Township.  Kittatinny Mountain forms the eastern side of Wallpack Valley; the western side comprises the Wallpack Ridge (highest elevation: 928 ft above sea level.

McKay Bay: McKay Bay is the name given to the northeastern corner of Tampa Bay, a body of water in Tampa, Florida.  The McKay Bay Greenway runs through the area on the east side of McKay Bay and connects to the Tampa Bypass Canal.  McKay Bay Nature Park is located at 685 North 34th Street in Tampa.  The area also includes the McKay Bay Resource Recovery Plant, a power plant fueled with refuse.  The lake was man-made and was once used as a cooling pond for a city incinerator.  McKay Bay is at the northeast corner of Hillsborough Bay, which is the name given to the portion of Tampa Bay on the east side of Tampa's Interbay Peninsula.

Saltonstall Mountain: Saltonstall Mountain, also known as Saltonstall Ridge, with a high point of (est.) 320 ft above sea level, is a traprock mountain ridge located 3 mi east of New Haven, Connecticut and 1.75 mi north of Long Island Sound.  It is part of the Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border.  Saltonstall Mountain is known for its 100 foot scenic cliff faces and sharp ridgeline, unique microclimate ecosystems, rare plant communities, and for Lake Saltonstall, a 3 mi long by 0.3 miles (400 m) wide municipal reservoir nearly enclosed by the mountain.  Saltonstall Mountain is traversed by a number of hiking trails managed by the South Central Connecticut Regional Water Authority (SCCRWA) and Branford Land Trust.

Sharp Mountain: Sharp Mountain or Sharp Ridge (historically also spelled 'Sharpe') in eastern central Pennsylvania in the United States is a ridgeline (fold) of the Ridge-and-Valley Appalachians cut through on its east-side in the Tamaqua gap by the Little Schuylkill River which sunders it from the eastern extension of the ridgeline, the Nesquehoning Ridge.  The ridgeline, located in the heart of the Pennsylvania Anthracite Coal Region, drains to the Susquehanna along its western slopes and via the Little Schuylkill tributary of the Schuylkill River on its eastern faces.
