'''Visuals:''' On a black background, there is a white line going into a circle. Inside the circle is a white/{{color|darkviolet|purple}} outline of a mountain face, with {{color|green}} trees below it. To the right of it is "Sierra" in a small script font and "'''''ON-LINE INC'''''".
'''Trivia:''' The mountain seen in this logo is based off Half Dome in the Yosemite National Park, which is located about 14 miles north of Sierra's headquarters in Oakhurst.
'''Variants:'''
*On their first title, the logo is in the middle of the title screen.
*On the PC port of ''Wizard and the Princess'', the logo draws in on a {{color|gray}} background. Here, the mountain is fully colored and the line and text are {{color|pink}}.
*The line and mountain may not be seen.
*On later games, the On-Line Systems logo (which is the same except the mountain is gone and the text reads as "ON-LINE systems") appears in a slash formation with 5 other copies. Each of them have "Presents" below them.
'''Variants:'''
*Usually, the logo would take up the entire screen, with beveled edges and a shiny look to it. 2 stars ping in time with the music, as well as it occasionally shining. The color differs from game to game, but it's mostly {{color|green}}.
*On some games, the logo is on a {{color|blue}} background, with each piece sliding in one by one. The name then appears below letter-by-letter, as well as "PRESENTS".
*Sometimes, the logo starts with the picture of an actual mountain (a picture of Half Dome at Yosemite National Park) before morphing to the logo, with the name brightening below.
*Later on, the text was modified to a Times New Roman font, and the logo is smaller and placed to the right sometimes.
*On other games, a {{color|blue}} furry monster walks in with either the [[Dynamix Software|Dynamix]] logo or byline, before pointing at the logo and saying the name.
*On the last games, the logo gained a metallic look to it, as well as the Dynamix logo.

'''Visuals:''' Starting off with Half Dome at Yosemite National Park with clouds rolling above, they move around as flashes of lightning brighten it up from the back. The camera then zooms into Half Dome, now with lightning striking it, before it brightens up and a {{color|gold}} circle zooms out slowly to surround it. A duller circle then stops around it, with the second one coming in and with a rainbow coming in from the side. Half Dome becomes {{color|gold}} and the rainbow hits it, turning it into a shining golden Sierra logo. "{{font|Serif|{{color|gold|SIERRA}}}}" zooms in from the screen as the light behind it dies down, before popping up again. The logo continues to shine.
'''Variant:''' On 1995 installers, the logo appears still with a ping on the top-left. This is likely the very first version of this logo. An abridged version of the standard Sierra tune plays.

'''Visuals:''' On a black background, the 1998 Sierra logo ("SIERRA" in a strange font with a wing of spikes on the "S") in a {{color|hotpink|pinkish}} {{color|silver}} zooms out letter-by-letter, starting with the "A". The logo also shines brightly the entire time.

'''Visuals:''' On a white background is the bottom of a snowy mountain. As the white clears to reveal a {{color|blue}} sky, it reveals the familiar mountain with snow and mist all around the {{color|red|reddish}} rock. As it zooms out, the background fades to black and the mountain fades to the logo, which is a modified version of the familiar mountain still moving in it. When it stops moving, a flurry of snow comes from the corner and takes the logo with it. It then clears out, with the logo fading back in, along with a modified version of the "SIERRA" text from before (minus the wing).
'''Trivia:''' The logo was originally produced in a full 16:9 widescreen ratio, however, every Sierra title would use a cropped 4:3 version, which itself was sometimes cropped into a matted widescreen ratio on some games. The only time you ever get to see the native widescreen version is through the warp-speed version introduced in 2006, and no game ever used the normal logo in native widescreen.
*Software released under the Sierra Home label had this logo with the word "Home" in a cursive font. This print variant was used until 2004, when the Sierra Home label was discontinued.
*On some games, such as ''Die Hard: Vendetta'', the finished logo fades out early.
*A still version exists, with the mountain and text in {{color|gold}}.
*A white-background still version is used on ''Tribes: Vengeance''.
*On the GBA version of ''Ice Age 2: The Meltdown'', it's a still logo over an {{color|lightblue|icy blue}} background.

'''Visuals:''' The logo starts with wind blow against a white background as a man clothed in hiking gear, shielding his eyes with his left arm, comes into view. As the wind dies down is the Sierra mountain, and the hiker pauses to view it for a moment before running up to it. The camera zooms out, revealing that the hiker animation comes from a series of {{color|blue}} bars. They come together to form a {{color|blue}}, redesigned version of the Sierra mountain emblem as "{{color|gray|SIERRA}}", in a stylized font resembling the one from before, forms underneath it. When the logo is complete, it flashes {{color|blue}} and some frost blows off of it, and the background changes to vignetted black/{{color|blue}} gradient.
