Geyser Rock is a location in The Precursor Legacy. A small island south of Sandover Village, it was used by Jak and Daxter to receive training before beginning their journey (serving as the game's tutorial). Although Geyser Rock could thereafter be visited via the teleport gate in Samos' hut, it did not contain any further missions or power cells.
The island's most prominent features include its namesake geysers, large Precursor robots embedded in the rocky cliffs, and its array of platforming challenges, unencumbered by any enemies as seen later in the game.
History[]

Jak training on Geyser Rock.
Before Samos Hagai would allow Jak and Daxter to journey north in search of Gol Acheron, he required that they train on Geyser Rock. In addition to trialing his basic combat (on inanimate scarecrows) and maneuvering, Jak was introduced to the value of Precursor orbs and power cells; his ability to interact with Precursor artifacts and other objects with blue eco; how to use green eco to heal himself; and how to collect Keira's scout flies for a power cell.
After collecting every power cell on the island, Jak was allowed to return home via the teleport gate and explore outside the village.
Geography[]
Geyser Rock is an island off the southern coast of Sandover Village, west of Misty Island, visited only by teleport gate. The island is completely uninhabited except by the brightly colored birds flying overhead, and butterflies closer to the ground.

The island is rather small in terms of expanse. Rather, it attributes most of its landmass to a spiraling structure of rocky cliffs and grassy plateaus, such that the final area of the level drops directly to the beginning area from a tall cliff. Various grassplots feature the level's beaten paths, though there are also sandy beach embankments that form makeshift paths. Scattered about are palm trees and shrubs, some of which curiously grow from the cliff facades.
One of the island's most noticeable features is its geysers, of which there are four, which intermittently erupt from large travertine formations, or cones. These eruptions give a near-constant mist in most areas of the island, giving the appearance of light rain (though it never rains on the island in the game). The first and largest cone is at the south end of the island, where the mission starts. In the northwest is a tiered embankment where scout flies are found, and the second cone sits in the water in this area. Off the beaten path of a southwestern beach lies the third cone. In the central area of the island is a small lagoon, behind a Precursor door, where the fourth cone lies.

The island has very few artificial elements in its environment; the most notable among these being the massive, broken down Precursor robots nearly fossilized in the various rocky cliffs. They appear to potentially still be functional, however, as during the night time, their light eco "hearts"[1] and eyes will glow. Other artificial elements include the scarecrows, used as training dummies; metal spike traps that recede into the ground; rickety wooden bridges and lampposts; and the various minor Precursor artifacts, including a floating platform, large Precursor drums used as platforms, and a blue eco vent.
