How to use the mindat.org media viewer

Click/touch this help panel to close it.

Welcome to the mindat.org media viewer. Here is a quick guide to some of the options available to you. Different controls are available depending on the type of media being shown (photo, video, animation, 3d image)

Controls - all media types

Zoom in and out of media using your mousewheel or with a two-finger 'resize' action on a touch device.

Use the mouse or your finger to drag the image or the view area of the image around the screen.

< and > at the left and right hand side of the screen move forwards and backwards for the other images associated with the media you selected. Usually this is for further photos of the same specimen. Keyboard shortcuts: use the left and right arrow keys.

> in the bottom center, raises the information box giving details and further options for the media, < at the top of this box then hides it. Keyboard shortcuts: use the up and down arrow keys.

? opens this help window. Keyboard shortcuts: use the H key or the ? key.

Other keyboard shortcuts:

1Fit image to screen
2Fill screen with image
5Display at full resolution
<Make background darker
>Make background lighter
spaceHide/dim titles and buttons

Controls - Video

Video files have a standard set of video controls: - Reset to start, - Skip back, - Play, - Pause, - Skip forwards. Keyboard shortcuts: You can stop/start video play with the P key.

Controls - Animation (Spin Rotation)

Animation (usually 360 degree spin rotations) have their own controls: - enable spin mode. Note that while images are loading this option will not be available but will be automatically activated when the animation has loaded. Once active you can spin the image/change the animation by moving your mouse or finger on the image left/right or by pressing the [ or ] keys.

The button switches to move mode so that you can use your mouse/fingers to move the image around the screen as with other media types.

The button, or the P key will start playing the animation directly, you can interrupt this by using the mouse or finger on the image to regain manual movement control.

Controls - 3D Stereoscopic images

Stereoscopic 3D image viewing requires a suitable 3D television or monitor correctly configured for your computer. Passive 3D systems such as LG 3DTVs are the easiest to configure for this.

To enable/disable 3D stereo display of a compatible stereo pair image press the 3 key. If the left/right images are reversed on your display (this often happens in full-screen mode) press the 4 key to reverse them.

Lucas Canyon has historically produced small amounts of gold, and this quartz crystal is likely a byproduct of gold mining in the canyon. This specimen was formerly in the collections of Wes Greenamyer & Gene Schenet, and Wes' specimen label for this piece notes that it was previously on display at the small gem & mineral museum (and store) that used to exist at Knott's Berry Farm (a western themed amusement park in Buena Park, California) dated 1998. Wes' label lists the exact location found as the 'Old Columbia Gold Mine' in Lucas Canyon, but no other written record of this mine name seems to exist. USGS topographic maps of the area from 1954 show three unnamed mining adits, and several old mining shacks that used to exist in this canyon (the structures burnt down in forest fires since that time), so likely this quartz crystal came from one of those adits. Rene Engel's 1959 article for the California Dept. of Natural Resources Division of Mines, titled Geology and Mineral Deposits of the Lake Elsinore Quadrangle, notes that placer gold was first found in Lucas Canyon in 1900, and that active placer claims existed in the canyon during the 1940-50s (named the Yvonne claims). The article also mentioned that the pay dirt was under 10-20ft of barren gravel and produced very little gold overall. BLM records show that in the 1970-80s several groups of people held placer claims and one group had a hard rock lode claim named the Busy Bee in the NW area of the canyon which suggests the existence of quartz veins in the canyon that could have produced quartz crystals. Additionally a news article published in the Los Angeles Herald, Number 279, July 6th, 1899, describes that locals had been finding occasional small placer nuggets in the Santa Ana mountains, and that their source was finally confirmed as Lucas Canyon, but that a lack of water was preventing any large scale mining operations. The article also mentioned 'good grade' quartz had been found in the canyon.
