Yes and no. A lot of the material that forms the San Juan islands are leftovers from glacial action. Material abundant on the islands that the glaciers brought includes most of the sand and gravel as well as 'erratic' boulders. Earlier features were also shaped and changed by the glaciers, but there are indeed rock formations in the San Juans that predate the Pleistocene (the most recent 20 or so glacial advances) glaciations. An interesting way to think about glacial effects (bringing material and changing the shapes and surface formations of material that was already present) to consider the southward advance and northward retreat of the glaciers.

Where is San Juan islands?
The San Juan Islands are a part of the San Juan Archipelago in the northwest corner of the continental United States. The archipelago is split into two groups of islands based on national sovereignty. San Juan Islands are part of the U.S. state of Washington, while the Gulf Islands are part of the Canadian province of British Columbia. There are over 450 islands in the entire archipelago at high tide, but fewer than one-sixth are inhabited, and only six are accessible by public ferry. Check links in the left column for more details
What is the term for all sediments of glacial origin?
Glacial deposits or glacial drift refer to all sediments of glacial origin. These deposits include materials such as till, moraines, outwash plains, and glacial erratics that are left behind by the movement of glaciers.
Which new york landscape feature was formed primarily as a result of glacial deposition?
Central Park in Manhattan was formed primarily as a result of glacial deposition during the last ice age. The park's landscape features, such as its hills, valleys, and rock formations, were sculpted by the movement of glaciers and the debris they left behind.
What type of terrain and landforms would indicate the prior presence of continental glaciers?
When the glacier melted from North America it left a mass of "heterogeneous" rock debris (loosely termed "glacial drift") etc
What are depressions left by melted blocks of ice in glacial deposits?
Kettle holes are depressions left by melted blocks of ice in glacial deposits. These features are typically surrounded by mounds of sediment called kames. Kettle holes are common in areas that were once covered by glaciers during the last Ice Age.
How does glacial till differ from stratified drift describe one glacial feature made of each type of glacial drift?
Glacial till is unsorted and unstratified sediment deposited directly by a glacier, while stratified drift is sorted and stratified sediment deposited by glacial meltwater. An example of glacial till is a moraine, which is a ridge of mixed debris left behind by a moving glacier. An example of stratified drift is an outwash plain, which is a flat, gently sloping area formed by the deposition of sorted sediments carried by glacial meltwater.
What Depression left by melted blocks of ice in glacial deposits?
A kettle is a depression left by melted blocks of ice in glacial deposits.
