This page details everything you need to know about how to complete the Explorer - Plank Cliff quest, which can be acquired from an ASL Terminal after speaking with the robot named BURG.L in the Oak Lab. We’ll cover where you can find the trail marker and what materials you need to construct it.

Where to Find the Trail Marker at Plank Cliff¶

The trail marker at the Plank Cliff is located near the center of the yard, directly south of the Oak Tree and west of the Toad Swamp, as shown on the map below. This area is fairly exposed in the open grasslands, so you could encounter Wolf Spiders, Orb Weavers, Bombardier Beetles, Larva, and Lawn Mites. However, you can always run away from them as you make your way up the plank, at the top of which you’ll find the trail marker.

How to Construct the Plank Cliff Trail Marker¶

To construct the trail marker here you’ll need 2 Sprig, 2 Plant Fiber, and 1 Clover Leaf. You’ll find plenty of clover leaves and sprigs to the northeast, especially closer to the pond. Plant Fibers can be extracted from most vegetation as you cut it down, but you’ll also get it from bits on the floor if you’re lucky. The springs are generally found throughout grassy parts of the yard, and often intermingled with the clover leaves.

Trail Marker Materials¶

Icon	Material	Quantity
	Sprig	x2
	Plant Fiber	x2
	Clover Leaf	x1

Once you have all of the materials to construct the trail marker, all you need to do is interact with it and press the key to build. You can then customize the icon and its color if you wish. This icon will be visible on your HUD as you wander through the yard, which basically means that you’ll be able to see it in the distance when you’re facing in the right direction.

How to Disable Trail Markers¶

With the trail marker constructed, you should have earned 100 Raw Science. You can always disable the trail marker from the map so that it doesn’t display on your HUD if you have no use for it, but it shouldn’t be too intrusive to leave on and they are very useful orienting icons.

Copying Trail Markers¶

You’ll notice that when you interact with the constructed trail marker, you have an option to copy it. You can do this to create another trail marker nearby, which you can also customize with its own icon and color. This can be useful to mark the location of specific Field Stations on your HUD, or to mark the location of a particularly good farming spot for materials / bugs. You can even just mark a site that you think is pretty, or place the marker at the top of one of your bases, for example.
