- MS-DOS (Wikipedia)
MS-DOS (/ˌɛmˌɛsˈdɒs/ em-es-DOSS; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as “DOS” (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system.

Located behind the Gorge Powerhouse in Newhalem, Ladder Creek Falls offers a refreshing woodland retreat with exotic flora and close-up views of the third tier of this spectacular waterfall. When the hydroelectric project near Ross Lake was under construction during the 1930s and ’40s, owner and developer J.D. Ross built a trail to nearby Ladder Creek Falls to showcase the area.
