You gather a variety of things in the mountain. From berries to 
mushrooms, to herbs to walnuts.

Spring

Veryberry Fruit-purple berries can be found in the woods and are worth 40G each. Once you pick one, it will not grow back until the next day. You can find 4 veryberries in the first spring, and only 3 in all the rest of the springs.

Medicinaly Herbs-The owner of the Potion Shop has been looking for these plants to make his medicine. Look for them in the cave. They are worth 70G. You can find 3 in the mountain a day.

Edible Herbs-These herbs, also found in the cave, are tasty but not as valuable as berries. You'll earn just 30G for each herb. You can find 2 of these in the mountain every day.


Summer

Tropical Fruit-During the summer you should hike the mountain area to look for freebies such as the Tropical Fruit. It was worth 40G and you can only find one in the mountain a day.

Walnuts-Walnuts are also found in the summer when you hike in the woods. AT 70G per nut, it's worth it to search for them. You can find 2 of these in the mountain a day.

Winter

There is nothing to gather in the winter, but you can go to work in the mine. 


Mining

Iron Ore-This looks like two gray rocks, it is worth 100G each.

Moonlight Stone-This is worth 500G each, it looks like crystals. Don't forget to save a few to give to Rick to get a Firefly Light in the second Summer.

Blue Stone-This looks like a blue crystal, and is worth 700G each. Give one to the Craft Store owner, and he'll change that red pot he never sells(because it was a mistake) to a blue pot which you can buy.

Rare Minerals-rare minerals are a greenish color, and are worth 1000G each. If you give them to Rick, something cool might happen!(wink wink)
