Google has sent their Street View cameras through the lower grove, and while you're certainly free to street-view your way over the entire mile-plus trail, you may prefer to see the highlights here first. Click the little bunch-of-arrows button in the top right corner of each street view to expand it to full screen, then click and drag inside the street view to pan it. It's particularly helpful to scroll around until you see people so you can get some sense of scale. Note that you can pan not only horizontally in a full circle, but vertically to a lying-on-your-back straight overhead view as well.
If you're on a computer with a mouse and a mouse wheel, rotate the mouse wheel to zoom in and out. Otherwise, click the plus & minus buttons in the bottom right corner of the street view to do so.
The Grizzly Giant is the grand old man of Yosemite's sequoias, 34 feet (10 meters) in diameter at the base and 1,800 years old.
If you're only going to click the upper-right-corner go-full-screen button on one of these street views, make it this one.
There are two sequoias in the grove with man-made tunnels in them (both carved out during the 19th century), but the other one,
the Wawona Tunnel Tree in the upper grove, fell over during a winter storm
in 1969. It turns out that cutting a great big hole in the base of a tree is not good for it.
This is a face-on view of the roots, a hard perspective to get with your more upright trees. The Fallen Monarch died more than 300 years ago, but the tannin-crammed wood is highly resistant to rot.
It's rare to spend more than a minute around this tree without encountering people posing in front of it, but somehow the street view cameras avoided that. Here's the closest available shot, a frame with a person passing by the tree to provide some useful perspective. Thanks for helping us out, blurry-faced-but-no-doubt-handsome man with plaid shorts and a red backpack.
When you're gazing at this gaggle of roots, which is around 12 - 15 feet high, imagine a tree trunk twice its size, and then you'll have some idea
of what you're going to encounter when you reach the Grizzly Giant, which is 34 feet in diameter at its base - a measurement
exclusive of the root cluster that makes this tree seem so impressive.
This view is not terribly far from where the photographer stood for
this circa-1900 photo
of dozens of members of the 6th Cavalry F Troop (including their horses) posing atop the Fallen Monarch.
This clump of trees is a happy sight for photographers looking for ways to photograph sequoias without turning their cameras sideways.
This spot is likely to be unrecognizable when the remodeled grove reopens in (hopefully) late 2017, but if you want to street-view-hike the entire lower grove trail,
here's where you start. The second-from-the-right kiosk is stocked with
this brochure (PDF)
in a variety of languages.
