Lewis and Clark Pass, el.
 6424 ft is a mountain pass on the continental divide in Montana.
 It lies at the head of the drainages of the west flowing Blackfoot River and the east flowing Dearborn River.
 The pass is in the Helena National Forest in Lewis and Clark County.
 The Continental Divide Trail traverses north and south through the pass.
 At the time of the Lewis and Clark Expedition the pass was a much-used pathway where the native people living in what today is Montana crossed over the continental divide.
 The pass was crossed by Meriwether Lewis on July 7, 1806, on the return leg of the Lewis and Clark Expedition with a party of nine men and his dog Seaman.
 The pass was named for the expedition's two leaders–Lewis and William Clark.
 Lewis and Clark Pass is the only roadless pass on the entire Lewis and Clark National Historic Trail.
 It has gone from being one of the most used continental divide passes prior to the pioneer era to one of the least visited passes today.
 It can be accessed by a 1.5 mi trail.
 Visitors will encounter the pass much as Lewis did in 1806.
 The furrows left by the countless dog and horse travois that crossed the pass are still visible (though fading) and this is one of the places along the expedition's route that visitors may still encounter a grizzly bear.
 On a clear day, like Meriwether Lewis in 1806 one can see Square Butte in Cascade County, Montana, 40 mi to the northeast.
Tulips is a 1981 American comedy-drama film starring Gabe Kaplan and Bernadette Peters.

Fast Break is a 1979 American comedy film.
 "Fast Break" stars Gabe Kaplan as David Greene, Harold Sylvester as D.C. and Bernard King as Hustler.

George Davies (25 December 1875–23 July 1959) was a Welsh international rugby union forward who played club rugby for Llandeilo and Swansea.
 A two time Triple Crown winner, Davies would represent his country on nine occasions.
 A skillful player, Davies was unfortunate to be playing during the same period as Rhys Gabe, who was the selectors' first choice at his position.
 It was all the more unfortunate for Davies as it was a collision between himself and Gabe, during a Swansea match, that caused an injury that would allow Gabe to take his position for Wales.

The Macaulay family of Uig in Lewis, known in Scottish Gaelic as Clann mhic Amhlaigh, were a small family located around Uig on the Isle of Lewis in the Outer Hebrides of Scotland.
 There is no connection between the Macaulays of Lewis and Clan MacAulay which was centred in the Loch Lomond area, bordering the Scottish Highlands and Scottish Lowlands.
 The Macaulays of Lewis are generally said to be of Norse origin because of the etymology of their surname and also because of the islands' Viking Age past.
 However, a recent analysis of the Y-DNA of men with Scottish surnames has shown that a large number of Hebridean Macaulays are of Irish origin.
 In the 17th century, however, tradition gave the Macaulays an Irish (or Gaelic) origin.
 By the end of the 16th century the dominant clan on Lewis was Clan Macleod of The Lewes.
 Other notable Lewis clans were the somewhat smaller Morrisons of Ness and the even less numerous Macaulays of Uig.
 The Macaulays were centred in the area surrounding Uig on the western coast of Lewis, and had a deadly, long-standing feud with the Morrisons, whose lands were located on the northern coast around Ness.
 Today the Lewis surname "Macaulay" is considered to be a sept name of the Macleods of Lewis.
 There are two other nearby clans of Macaulays who may, or may not, be connected to the Lewis clan—the Wester Ross Macaulays, and the Uist MacAulays.
