However, other causes — including long-term increased precipitation and geologic bedrock structure — could be important contributing factors in their formation.
For one site, a conclusive inference on bedrock depth could be drawn, whereas for the other site vital information regarding subsurface geology could be extracted.
Although for this particular site no conclusive evidence on bedrock depth could be drawn, both the methods provide fascinating vital information on the subsurface condition.
This study shows that bedrock uptake could be an essential water balance component of semi-arid, mountainous pine forests and should be accounted for in hydrologic models.
The specific landing site was between two young impact craters, North Ray and South Ray craters – 1000 and in diameter, respectively – which provided "natural drill holes" which penetrated through the lunar regolith at the site, thus leaving exposed bedrock that could be sampled by the crew.
In any case, one thing has been certain, that with the support of its founding sponsor American Express, the festival had the secure financial bedrock from which it could be nurtured into a yearly event sustained by more than its original rationale for existence.
The results show that no bedrock (either engineering or geological) could be detected here at this site, as Vs does not exceed 760 m/s.
The size and cost of the heat storage are the main drawbacks of this technology but using crystalline superficial bedrock as a heat reservoir could be a readily available and cheap solution.
Howard Schultz, the CEO of Starbucks, is leading a movement of business leaders and political donors to end the hyper-partisanship in Washington that could be the bedrock of financing for a viable independent, bipartisan, ticket for 2012.
